Thank you so much dude! This helped to finally wrap my head around how it worked after researching so much. You explain it super well and the examples make all that much better. Great job! ❤️
Why is the last question sex linked? I heard from another person that if its sex linked then the Mother affects sons or Father affects daughters, which I dont see on the pedigree...
#3 is 100% recessive. Do your punnet squares. If question#3 were a dominant condition then all of the children of 3 & 4 should be healthy because the recessive allele is healthy. You can also see that #3 is recessive because 7 & 8 are affected and homozygous recessive so all of their kids are affected and also homozygous recessive.

You taught me a much simpler and easier way to solve it than my teacher did. Thank you!
Great video, very informative, helped me a lot!
Thank You so much for this video.... Helped me a lot!! ❤️❤️💕💕💕💕💕💕
Very good way of explaing this, thank you!
Was the third pedigree autosomal or sex linked? I’m still a bit confused
wait, so is the 3rd pedigree autosomal or sex-linked? I did not hear a definite answer...

i 100% agree
hello, I have a question and I hope you can help me out! where can I send you the question if that's possible? Pedigree related
Awesome job. Thank you
so helpful! thank you so much

Did I say something different? If you are talking about the 3rd and final example then we agree that is recessive. Look again at 4:24
You forgot about y-linked diseases?

The 3rd pedigree is dominant
It cannot be dominant. Look at parents 3 and 4. They have an offspring (9) that has the disease.
For me, it is autosomal recessive
@@biokks5245 but what about parents 1 and two?
@@gæaf Parent 1 has the disease so shell will be homozygous recessive (i.e aa) and parent 2 is heterozygous in order to be healthy (i.e. Aa).
