I did not understand what is meant by heritability
Why is it applied to twins if genes are inherited from parent to child?
How readhedness is 100%? I understand Mendel study in school is simplification, but you can get all sorts of gene mixes in kids
> Why is it applied to twins
Identical twins have the same DNA. Any differences between the 2 of them is not genetic. Studies of twins are very important when you try to separate "nature vs nurture".
I highly recommend the author's other post https://dynomight.net/heritable/
