BROTHER I WAS SO PUMPED WATCHING THIS VID I HAD SEVERAL EUPHORIC MOMENTS THAT I MUST DECLARE... AT FIRST I WAS LIKE WOA NAH BRUH I DON'T GET ANY OF THIS BUT THEN I WAS LIKE WOA YAH I GET THIS AND I'M SO GRATEFUL THAT YOU PUT THE TIME AND EFFOT INTO MAKING THIS BECAUSE REST ASSURED YOU HAVE HELPED AT LEAST ONE PERSON IN THIS WORLD. I'M BUZZIN FAM.
I needed to know this for a college assignment, but because we are currently not having lessons because of the pandemic I had to learn it by myself. And i am so glad this video exists because I was so lost.
Great video, i will definitely be watching a lot of your videos on my week topics. Shame I found course late, cant justify spending the money at this point :P
Freddie Farrell Hello sir found it so helpful thanks a lot!!! But I still don’t get why the ratio is 3:1, because even though the genes are linked, I still get all heterozygous dominant for example , 2Tr and 2tR, which is after independent assortment!
Could someone explain the point made at 11:20 about the numbers and how they are a result of crossing over please (would we expect a phenotypic ratio of 4:3:3:1?). Thanks
Hello SIR found it so useful thanks a lot!!! But I still don’t get the idea that i]the ratio will be 3:1 after independent assortment because I will get all heterozygous and the genotype is 2Tr:2tR. Could you please say something more about this?
Quick question: the ratio of the phenotypes after the crossing over is 50% same as parent and 50% new. How does most of the offspring then have their parents genotype?
How is it that the closer the loci of genes of an autosome the more closely linked they are? I don't understand the crossing over diagram you drew with Q and q😭 Pls pls reply😭😭💓
how do you know which allele is on which homologous chromosome when the question tells you the genotype of the parents to be crossed it doesn't specify...?

But if crossing over always gonna occur that way around why we dont get ratio like 497:490:496:506 for example. I mean crossing over always swaps r allele and R allele everytime assuming crossing over always occur the same.Im confused about this hope u can clear Great video Thank You.

someone please give this MAN A GOLD TROPHY these are such a great aid for biology!
he dont want a gold trophy but he will gladly take ur money instead lol
These videos are the biggest a level biology help ever its like an individual lesson on each topic
I needed to know this for a college assignment, but because we are currently not having lessons because of the pandemic I had to learn it by myself. And i am so glad this video exists because I was so lost.
Hands down the best Biology tutorials on youtube! Good work folks!
Thanks so much! My course textbook was very vague around this topic, but your video cleared it all up for me. Very useful
Your awesome God bless you, I am being dead serious you couldn’t be any clearer I wish you were my teacher😭😭😭
Tailored Tutors thanks
great way of explaining thanks ur saving my grade
This is explained so well. Cheers g.
Who else is here the morning of their exam 🤦🏽♂️😂
Lol
Totally not me lol
Thank you so much you legit just helped me pass a test! :)

incredible
Wow I finally understand , thanks so much
Great video...thank you!!
Glad you liked it!
finally get autosomal linkage thanks
thank you you're amazing
OMG I GET IT NOW!!!!
SO glad!
Thanks this is a good explanation
Excellent. Thanks xoxo
The textbook explanation of autosomal linkage kept confusing me, thank you for making it clearer, I get it now!
In 11:55, if the chromosomes are closer on loci and hence have a closerlink, how does that affect how they are crossed?? I rly didnt understand that
really helpful and very much appreciated!!

it was perfect thank you . understood perfectly.
Awesome video, thanks for the help! :)
So helpful! :)
Thanks Khadijah!

amazing you're lifesavers
This video was so helpful. Thank you so much.
How is it that the closer the loci of genes of an autosome the more closely linked they are?
I don't understand the crossing over diagram you drew with Q and q😭
Pls pls reply😭😭💓
Oh wait the rqs stayed the same after crossing over but tqs changed 50% after crossing over!! Is that it??*_*
Your videos are great for revision.Keep up the good work,sir!
why will the majority of offspring have the same phenotype and genotype as their parents?
how do you know which allele is on which homologous chromosome when the question tells you the genotype of the parents to be crossed it doesn't specify...?
isn't the parents genotype like TtRr??
if the question states that the parents are heterozygous for both genes
They should show you a picture on the autosomes
thank u
If it is autosomal linkage, how come you are describing meiosis because autosomes replicate by mitosis.

Great video Thank You.
One more question, If we talkin just about Q/r and R/r (the close ones) what would be expected ratio?
