Mr. Anderson you are so helpful to me. I can take an hour or two in class learning about this stuff and after I come home my dad asks me what I learned, I will just babble, I will basically just say what comes out of my mind even though it does not apply to the lesson, but when I watch your video there is sure something to learn in so helpful. so helpful.
so thankful to mr. anderson., i really hate biology, but i doesnt have a choice now but to love it, due to my job...and your videos really help me a lot to ease up my tough times...thank you so much., its very essential
THANK U U ARE AWESOME thank u for the time u put into all those helpful graphics too like highlighting the chart for multiple gene trait thingy lol :D its helpful
Just watched the part about color blindness with my students. Thanks for another helpful video! One student asked about the glasses that are supposed to help color blind individuals see colors. I'm curious if you have tried these and could comment on their effectiveness.
It´s not an evoloutionary advantage, as you have heard to be colurblind it´s of course, the contrary, but from the beginning we had coluorblindness just like the other predators (not raptors).
In the tutorial and example of the gene linkage, you assume the less common case of incomplete dominance - the height is simply the SUM of the dominant genes. If we rather assume a Mendelian case instead, we can still get a bell shaped curve. The best way to see this is to regard any of the genes as a statistical variable whose possible values are say, 0 and 1, and define the height as the sum of these Bernouli variables. What we get is a binomical distribution, which approaches a bell shaped curve for a large number of genes (dozens and dozens, as you said). If we want to describe equal odds for a parental contribution of 00 01 10 and 11 resulting in the conditional activation of a gene (0, 1, 1, 1 respectively) then the probability of each Bernouli variable will be 3/4. The average height will then be 3/4 times the number of such genes.
Some genes on the same chromosome n they travel together = gene linkage , the percentage of them being distanced from each other on the same chromosome is less than 50 percent then the genes are linked and cannot be independently assorted. Depending how close each genes are to one and another, if they're 17% 'apart', then, in gene mapping, they are 17 units apart from each other
You're very helpful. Thank you so much for sharing your knowledge and teaching us in a very interactive way. My lectures are so bland and dry and my teacher a such a heavy accent. My book is absolutely confusing. So thank you.
That'd be awesome if you could do a whole video on epistasis. I tutor AP biology, I would say just about every single student doesn't understand it. To be honest, I don't really fully understand it either.
This was a great and interesting video. I'm really struggling with the probablity portion of my intro to genetics class after seeing that wonderful video which made hours of reading much clearer I hope there is a video on that. Although the simple display with the Punnett square and the height gene was actually pretty helpful on that front. You must be a great teacher.
This video helps a lot to people how need to know broadly about non Mendelian genetics. however, I need know more specifically to epistasis such as recessive epistasis and dominance epistasis. Does anyone know about a good video that might help me??
Please do a video on genetic mutations because I need some help understanding it. I learn better from videos than textbooks and you explain these topics very well. Please and thank you for if you actually make the video.

one day before my Biology exam and only this guy can help me!!
Paul Anderson is so helpful to me, he explains alot
you are such a great teacher , youve helped me with my biology A-level so much, i have my final A2 exam this week, wish me luck ! Thanks again
I saw the video was 14 minutes long at first and I went "ugh" but I couldn't stop watching, and when it ended I was sad. It's just so interesting!!!
Am I slightly color-blind or was 56 harder to see than the other two numbers? I could see it... but just barely.
I could only see it if I tilted my computer screen back, don't worry, you're not color blind
When Mr. Andersen says "I hope that's helpful" but ends up being my AP bio god
I need more help on epistasis :(
Thanks a lot for the vid, it was really helpful!
so thankful to mr. anderson., i really hate biology, but i doesnt have a choice now but to love it, due to my job...and your videos really help me a lot to ease up my tough times...thank you so much., its very essential
Am I the only one who could see all the numbers but 56??
wow u are such smart
one day I'll have such science too
Refrigerator
a haiku by doge
I'm sorry for being weird
is the 56 clear to anyone? cause the 49 looks like a 44 to me too... i can barely see the 56
your videos are amazing! thank you so much
So why doesn't incomplete dominance apply to larger organisms likes cows, even though it applies to plants?
THANK U U ARE AWESOME thank u for the time u put into all those helpful graphics too like highlighting the chart for multiple gene trait thingy lol :D its helpful

WOOT These are so helpful.
Where do you live? why can't you be my teacher :( My bio teacher sucks!
bro what tjhe phuck are my thumbs they look like toes?!?!?!?!?!
Currently prepping for MCAT and came across your videos. You are a great resource. Thank you.
Hope youre a doctor now
Look closely, you should see a light pink 56.
56 was hardest

I have one of each thumb-types xD
I remember a biologist on radio saying the word "epistasis" cropped up when geneticists didn't really know what was going on.
I DIDNT SEE ANY OF THESE NUMBERS. ?

Did anyone else notice that at 10:20 all the phenotype frequencies are the coefficients of binomial expansion of (A+B) to the sixth power?
Weird...
🤔
Kudos to passing bio goes to you dude
Do you have a video explaining the bombay phenotype? I'm trying to get my head around that.
Awesome explanation

Is there a teacher of USA award? Because you deserve it.
I'm a lesbian
Love me a shorthorn cow! From an Aggie taking genetics, thank you so much!!
Thank you so much this helped a lot for my quiz tomorrow
11:40 colour blindness explained well
Turns out its not actually there...
Thanks for the video! You make intro genetics stuff painfree.

Very helpful, thank you! =)
Your videos are amazing! Thank you so much for uploading these. :)
Troll colorblindness charts.
Thank you sir, this is really helpful
thank you for this video!!
Thank you!
fehckin gey
sir u frm which country/
Color blind gang
HE TALKS TOO FAST!!!!😭
wow thanks to you i still failed THANKS!!!!!!!

Please and thank you for if you actually make the video.
