Let’s start with genes.
Genes are sections of DNA which code for a specific trait.
You have literally thousands of genes. You have genes for eye color, hand size, metabolism, cell structure, and every other piece of your body.
It’s not as simple as one gene for one trait, but most basic biology classes discus it this way for simplicity.
Let’s move on to alleles.
Alleles are different forms of the same gene. Think of it as a different flavor or variety. Let’s use an analogy; if Coke were the gene, the alleles would be diet, classic, caffeine free, vanilla, cherry, or whatever kind of coke it is.
Using the eye color gene, the alleles could be blue, green, brown, grey, hazel, Just the different options for eye color.
Just remember, the gene specifies which trait and the allele specifies what form the gene takes.
And that’s it. Check out my other genetics videos, and if you have any questions, throw them in the comments.
Best explanation ever👍👌
Thank you!
nice,👍👍👍
Thank you!
Its true most understanable explanation ever
Yesss !
Thank you for explaining in 1:26 minutes what my teacher doesn't in 50 minutes
You're welcome!
True
Kakaka exactly
For real💯💯💯
my word i know how you feel
oh my god you're a life saver literally have been lost in my Bio class since Day 1. Been taking this course for two months failed two exams. Watched all your videos for 12-15 minutes, and it feels like I know everything now! passed last two exams and finals exam. best explanations ever!!!
This comment made my day! I'm so glad I could help!
damn... you explained this thing in a minute better than other videos of 10 mins... cheers
Short , clear and simple. Very helpful mate!
Glad you enjoyed it!
a week after my teacher introduced it i had no idea what the difference was, and in 30 seconds you said alleles are flavors of the gene and i hit me so fast
Genius explanation! It's so simple yet my teachers manage to make it so complicated! Thank you!
That Coca-Cola example was so simple yet so effective. Thank you!! Now I'll never forget :)
I thought it was pretty great too.
Thanks for explaining it in just 1 min..
Best explanation ever👌👌
Finally after struggling so much to understand difference between gene and allele, I found your video and understood everything in just a min..👌😊
this is the best explanation out there!
Thank you!
Thans you so much man i’ve been struggling to understand alleles
To be connected to the subject
Aftr yeeeeeeeeeeeeeears...
Forgetting
Re-remembering
Is
Refreshing 😊
Indeed!
Really great explanation, I feel like we run throw those concepts too fast in class so I really needed that solid clarafication
took me 3 years to understand I LOVE U
I spent 45 mins in class listening to my teacher talking about gene and alleles, but still can't understand.
BUT I SPENT 1 MINUTE AND 20 SECONDS AND I CAN UNDERSTAND IT NOW
._.
Thanks so much. I din't even get the differnce and the dictonaries didn't halep me in any way!
nicely explained
Thank you 😃
Short but effective 👏😃
The best of both worlds 😊
Searched This Type Of Explanation For 1hr...
I'm sorry it took that long, but glad you found it.
Really liked the explanation 🧬
Thank you for your explanation, can one code for more than one trait
Yes, absolutely
Thank you Sir
WOW!! didn't expect coke in Biology. Anyways thank you, the video was a quick help for my doubts.
Coke, especially Vanilla Coke, is essential in biology.
Why vanilla coke?
Good explanation sir
Thanks a lot..❤️❤️
You're welcome 😊
Sir. I have one doubt, If person with O blood group donated blood to Person who has AB blood group Don't it agglutination?
Thanks from IRAQ 🌸
You are welcome!
oh it was too good ! 👍👍👍
;)
oh it is easy way to catch the difference between gene and allele
Absolutely!
what causes variation ?
genes or allele
Osm example 👍😁
Allele is mixture of 2 gene ?
Over 30% of genes in the human genome are of unknown function (Leonetti et al., 2016) and even annotated genes have additional functions yet to be uncovered. Furthermore, even when a gene’s normal functions are known, methods are lacking to predict the functional impact of the millions of genetic variants found in patients. These gaps must be filled in order to convert the promise of human genome sequence data into clinical treatments, or in other words, into actual observation and treatment of disease in patients (including experimental treatment) as distinct from theoretical or experimental exertion.
Great!! !!
You came here to study for a test?
Many do.
Practical 😂exam
I know nothing
yes😢. and I'm analysis from iraq
Exam yup
im french and i dont understand this lesson in french but i understand it in english 😂😂😂😂
I'm glad I could help.
Saame, but for me it's Dutch, I'm glad most terms are very similar to Dutch, because I couldn't find a good explanation
Same but my mothertongue is HINDI and I cannot understand in hindi but in english😂😂😂
@@neetupandey9598 My mothertongue is also Hindi but I prefer mostly English lectures

Simple and straightforward--exactly what I needed. Thank you!
You're welcome, glad you liked it.
true, I was looking for something like this too
Been trying to understand what an allele was for almost a year, and you explained it in less than a minute, thank you a million times.
Wow! I'm sorry it took you so long, but glad I could help! Sometimes you just have to hear it a certain way.
So it means Height is Gene and Tall dwarf is allele?
Yes😅
Yes.
Yesss
I literally searched every video but I finally get it thx
I'm so glad you found what you were looking for!
Yaa
now i understand the difference between gene and allele .Good example with the coke easy to understand thank you.. could you do science for ged please? especially with writing extended response? also how to write an essay for science , im having trouble with writing an essay. thankks for the video
I'm glad I cleared a few things up for you Trisna. I will have to look into the GED science requirements and see what I can do. As far as the writing in science goes, I would think you can just treat it like any other writing assignment, but on a science topic. So the trick is to pick a science topic that you are familiar with and/or enjoy, then the writing will come much more naturally.
THANKS I HAVE AN EXAM TOMORROW AND THIS HELPED ME ALOT
So glad, I hope you crushed it!
how did it go???
I have an exam today and I was worried I wouldn't get it until I found this
someones probably already said this but who else is here for school work?
Many, many students. And hopefully they've saved a little time in doing so.
Simple , sober and accurate in about a minute .. legendary ! Loved it ... thank you sir 🙏🏻
sober? 🤣🤣
So concise and clear! You are a gifted teacher! Thank you!
Thank you, you are very kind.
I just want to say THAANNK YOUUU SOOOOO MUCHHHHH !!!🌷🌷🌷🌷🌷🌷 ... SERIOUSLY I want to like this video more than one time!!!!! The Best explanation i have never ever listened!!!!!!!⚘A rose from me!
Stay blessed and do more best ♡♡♡♡

Wow! I watched about an 8 or 9 minute video trying to figure it out. I wrote stuff but it wasn’t so straight forward. Your short video focused on just the two things and pinpointed the differences with simple bulletin points and good analogies. Great job, thank you!
This is the best summary I have seen about what I try to do on UA-cam.
I'm so glad it helped.
@@2MC I see you’re a great and dedicated worker because you saw my comment on a video from 2017. Great interaction and communication skills. I can spare the time to subscribe as a simple way to say thank you again. Awesome effort and content, keep up the great work! :)
OMG --- WOOOW :D You are so good! Thanks alllot :D :D :D Thank you, thank you, thank you allot ❣
I understood more than the last 10 hours of my reading trying to figure out what an allele is :DD
Glad it helped!
He explained in 1.5 minutes what my nursing school text could NOT explain in 3 large pages of fine print. THANK YOU!!
Sometimes textbook authors forget what it's like to be a student.
I'm glad I could help.
That blew my mind! I was searching for the difference and finally understood!! Thanks a lot🖤💖
My 5year old brain liked the coca cola example, really simplified it - I shared the video to help others understand
THANKS A LOT!!!
KEEP GOING
Glad it helped!
Genes represent traits for example there are gene for eye colour then how come there are 2000-2500 genes to represent a particular characteristic like eye colour. In a pair of particular chromosome i learnt there are two traits like blue eye and brown eye so are these the 2000-2500 genes making up each trait
Correct. We just simplify it for education purposes.
Thank you so much, I really needed the difference
May the Good God bless you
#JesusAddict😇🙏🏿✌🏿 Matt5:48
You are welcome.
Oooh thank you so much for this...👌🏻
I appreciate it...💯
😘 simple yet concise, I like that.... but i still have a question: if allele specifies the form a gene takes, does it mean that two or multiple alleles make up a gene? Or it's more like an allele is basically a gene [but just a different form, like how (from the coca cola analogy) there can be vanilla coca cola (allele) but it still basically a coke (gene)]?
There can be many alleles for a specific gene but each person only has two alleles, one from the mother and one from the father. Sometimes one allele is dominant over the other. Sometimes both alleles are expressed equally. Sometimes it's a mix.
In reality most traits are the result of multiple genes working together.
@@2MC 😀 I'm very glad you could reply, Sir.... I get that, but what I'm trying to ask is that, (since Vanilla coke is still coke) is an allele still a gene? Or a single gene constitutes two (or even more) alleles?
A gene is a section of DNA, that is all. Every gene (section of DNA) can have variation in the genetic sequence. Each of these variations are an allele.
@@2MC oh okay, I now get it... thanks very much
Question: I have hazel eyes. Do I only have the allele for hazel eyes or do I also have the allele for brown eyes but doesn't get expressed?
Although I simplify it for the video, eye color is controlled by more than one gene, and thus, there isn't really a single allele for hazel eyes or brown eyes or any other color. There are multiple genes with multiple alleles that contribute to your eye color.
One of the best vedio on UA-cam, examples are awesome, Thanx Bro.
What a complement! Thank you!!
im just having a cry laugh because i got a headfuck with this concept
HI I wanted to ask about the term ' non-allelic gene' does that means that it's just a gene that has a single form? Sorry I don't know if you understand what I'm confused about but basically I thought all genes has alleles . I saw this term from epistasis
These are genes that are not expressed as ellelic genes are but can affect allelic genes via epistasis.
This video is such good that 25 mins videos of same topic is not that much well.
you should do some hybrid and dihybrids, co dominance, dominance etc - but great video / love the content
Thanks Finn. I definitely have plans for those videos, just not sure when they will be produced and posted.
Sir this video is very helpful ....but can u give more examples ...becoz although i got it but still feeling confused ...plz sir help me .....
The gene has a set function, maybe eye color, or height, or making a certain protein. The allele refers to the way that gene is expressed. So a gene for eye color could have an allele for the color green or blue or brown. A height gene could be a an allele for tall or short. The allele for a gene making a protein could specify some shape or structural component of that protein.
I hope that make more sense. Essentially, the allele is a more specific representation of a give gene.
If i may ask, i understand what an allele and gene means 'physically', but what does an allele mean genetically? is it simply a varied genetic sequence, or is it a change in a single base in the gene of interest? been thinking about this all day :(
Great question! An allele is the genetic variation of the gene. For example, let's hair color has a single gene. One allele (variation) of that gene would code for blonde hair and another allele would code for black hair, another for redheads, etc.
And the differences would be in the genetic sequence of each allele.
Does that make sense?
i never understood this in high school for like 3 years. im in my 3rd year of college and it came to bit me in the ass. You made me understand this in 1 minute while all the professors i had never did this.
I'm sorry you haven't had a clear understanding of this for so long but am thrilled to be able to clear it up for you 😊
مُبَسَّطٌ و مَفْهومٌ
Simple and understood
🎉
I'm from Holland I totally can not understand the lessons but I watched this and immediately i really understand it
THANK YOU VERY MUCH 💜💜
I'm glad I could help.
Your example of coca-cola...
Superb sir.
Thank you, it's one of my better analogies! 🧐
Found out the reason my hair is born. A lot of my great grand parents are from England.
Nice!
This 1 min video is the best ! What a explaination !
Sometimes shorter is better.
Yep. Definitely the best. Thank you🤙👍🤙
*Hey🤔
Would Love To Have Some Clarity On This:
i.e., For Eg: When We Talk About The Genes for Height; Its Either Tall(T) Or Dwarf(t).
So, My Question Is; Is Dwarf also an expression like Tall or It is the absence of the expression Tall(T).
(Got Confused; When Heard Of Modified&Unmodified_Alleles; Cuz' It Said Unmodified_Alleles Are Dominant & Can Modify a Recessive Allele)
. . .
I Know Am Quite_Mixed Up Right Now; Sorry :)
Genes get very complicated very quickly. In some cases the recessive allele is the expression of a different trait and in some cases the absence of a particular allele may cause a different expression.
There are lots of genes which decide that phenotype right? And I think the total no. of T alleles in all of those genes decide how tall that person is going to be. Not very sure tho..
OMG THANK YOU!!!! Lifesaver! Thank you for the simplicity!
You're welcome Shelby!
If T is an allele for tallness...then can (TT) and (Tt) be called *GENES* for tallness?
Not quite. (TT) and (Tt) would be genotypes for tallness.
I never knew the diff between gene and allele until stopping by here........tqsm for this easy peasy lemon squeezy explanation🙏🙏🙇
You are so welcome 😊
So there can be more than one gene for one trait, for example, the height. And the allele of the height is located somewhere in the chromosome?
There can be, and often is, more then one gene contributing to a trait, this is called polygenic inheritance. However, I don't think that is what you are asking about. Alleles are various forms of a single gene, so for the height gene there could be an allele for short and an allele for tall. This is an oversimplification.
Essentially, the allele is the form of a gene and contributes to the trait.

excellent vedio crystal clearing my confusion thank-you very much
You're welcome!
you should be a teacher at a school, you would finish a unit everyday, accept that would be a lot of tests,
I was a teacher at a school. I quite enjoyed it.
What does it mean.. when the definition of alleles is " A pair of contrasting character of traits "
That is a very odd definition. Alleles are the variations of a specific gene and those alleles can be represented in character traits.
Love this video! Really helped me!
I think you should make 2 minute math videos! You've got the talent! But keep em 2 minutes.
Thanks Mike, I really appreciate it. I would like to get some math videos going as well. Any suggestions?
I would suggest that you start off with what they test on the GED (so you have a guide of what to teach). Then move on to college material.
So how exactly are alleles placed in the gene? I know genes are a section of DNA, so are alleles a section of genes? Or is it a section of DNA as well?
Great question. Alleles are the variation of the gene. For example, a gene for height could be the tall allele (variation of the gene) or the short allele.
Does that help?
@@2MC So alleles control what a gene codes for?
understood in 2 minutes which i was struggling from years to understand...
Glad I could help!
PERFECT! Thank you. Google was stressing me out.

Many human diseases are caused by particular changes, called mutations, in patients’ DNA. A genome is the complete DNA set of an organism, which contains all the information to build the body and keep it working. This information is stored as a code made up of four chemicals called bases. Humans have about 30,000 genes built from DNA, which contain specific sequences of bases. Genome sequencing can determine the exact order of these bases, and has revealed a long list of mutations in genes that could cause particular diseases. However, over 30% of genes in the human body do not have a known role. Genes can serve multiple roles, some of which are not yet discovered, and even when a gene’s purpose is known, the impact of each particular mutation in a given gene is largely uncatalogued. Therefore, new methods need to be developed to identify the biological roles of both normal and abnormal gene sequences, or in other words, abnormal genetic blueprint
Each form of expression is determined by a different allele of the colour gene what does it mean?
I'm not sure what your question is.
@@2MC this is same line written in my books
Thank you so much for helping me with it. I've been struggling with it for so long and you made it so easy for me in just 1:26 minutes! Keep posting videos like them. You're doing awesome!
Thanks! Just trying to give you the information you need in as little time as possible.
@@2MC I hope you are still responding to comments because I still need clarification.. I have someone trying to explain allele to me as a mutant gene because alleles arise due to a mutation in a gene. So when you say "different form of the same gene" are you in essence saying "a mutant form of the gene?"
Save this guy at all costs.. Legend.. 2 years worth of confusion solved in 1 minute. Wow.
Thank you my friend.
So is it correct to say that alleles have different DNA sequences? Because the gene that codes for a blue eye color for example will be different from the gene that codes for a red eye colour
After all, the actual information stored by genes is in its sequence of bases💁🏾♂️
I want the difference between gene and allele in terms of A,T,G,C. Base pairs.
A gene does have specific base pairs, it is the allele that determines the base pairs for a specific gene. That's like asking about the difference between a soda and a Vanilla Coke in terms of flavor.
@@2MC Thanks for the reply.
Bhai bass bottom line nahi samjha aai😅
