Used pretty much all of your videos to study for the MCAT. I'm now in my second year of Medical school and I'm still using these as a resource for review! Thank you for all your work and dedication!
i love the depth of your vids but you build redundancy into your presentation better than codon triplets, i tone out every now and again for a little , rewind and relisten.. but nothing was missed
I would assume so. There are probably more complex genetic mapping expressions that might talk about recombination frequencies of multiple genes/alleles, but I think that as a measurement, recombination frequency has to involve at least 2 different genes/alleles
"The likelyhood (possibility) of the 2 genes crossingover separately is inverse to the distance between them." So lets break this down 1. inverse: means that when one goes up the other goes down. 2. in this case chance of crossover is = to recombination freq. 3. Linked genes are less likely to crossover. 4. Recombination freq can is equivalent to gene distance=gene Map unit distance=centimorgan units. 5. Farther apart (large distance) means they have less likely chance of being linked (if on same chromosome) Heres how to remember this: " The Farther apart you live the less likely you are to cross into one another." (more distance=less linkage)
Recombination is a big thing among black Americans many of us are predominantly white but majority black due to recombination. My dad had chromosomes with 80% Caucasian while being 78% black on the sum of his chromosomes this is how we have white appearing black people this is a great way to explain the black American race in America. Some people assume that it means you have a lot of white ancestry why someone would look mostly white while being black the white ancestor could be very far back and very few it's a matter of recombination because the chromosomes range

Good luck at school (replied because your comment is new in this old video)
agreed!!!!
Finally understood linkage, my expensive professor could not do a job as good as this free explanation, thank you!!!
Exactly what i needed. Thank you
So easy to understand, thank you so much!

Thanks for watching, I will try to improve upon that in future videos.
thats on you bud its not hard to pay attention for 10 minutes
Just finished watching all of your videos. Excellent work! Thank you
Oh so handsome and a great instructor. 😊😊
The best explanation!
From Pakistan ❤💚🇵🇰
Is recombination frequency usually expressed between two alleles as in your example, i.e., Eb at 93% and EB/eb at 7%? Thanks!

I don't even care how long the lecture is if he's gonna be the teacher 🤩😅
Good looking and smart
best linkage😝😝😝
Well explained.....from India🇮🇳
Yes ! Really concise, thank you
How is the probability of crossing over will occur between two loci increase with the increasing of distance between two loci on the chromosome
I agree with u in that question..
What's this guy's name
Sir plet I want more lectures.
so... if its linked = less likely to crossover?
Yep
Crossover will still be there but the chances of separating the linked genes is very less.
Sir,9:13-9:26 ,I didn't catch what you said.
The rest i understood in the best possible manner.Thanks
"The likelyhood (possibility) of the 2 genes crossingover separately is inverse to the distance between them." So lets break this down
1. inverse: means that when one goes up the other goes down.
2. in this case chance of crossover is = to recombination freq.
3. Linked genes are less likely to crossover.
4. Recombination freq can is equivalent to gene distance=gene Map unit distance=centimorgan units.
5. Farther apart (large distance) means they have less likely chance of being linked (if on same chromosome)
Heres how to remember this: " The Farther apart you live the less likely you are to cross into one another." (more distance=less linkage)

I cant understand
All my doubts sorted sir thankyou 🙏🏻
Thank you so much 😊sure gonna ace this test💃
helped a lot thank you sm for the video!!!!!
Don't you mean genes instead of alleles?
thank you sir! That was a wonderful explanation
so linked genes cannot recombine?
They're less likely to, yes
Yes, they can recombine! It's more unlikely
🐐🐐🐐
excellentttttttttttttttttttttttttttttttttttt.... hats off from pakistan
Thank you sm ❤️
Best explanation
wow😊😊👌
