If blue eyes are regressive (overridden by brown eyes) then, how could millions of north Europeans end up with blue eyes, supposing that blue eyes come from a single mutation?
In: Biology
you cant use punnett squares to predict eye color, even though a lot of schools like to simply and teach it that way in high school it’s a huge oversimplification. It’s more complicated than just blue or brown. What about green? Hazel? There’s many kinds of eyes that are in between and a lot of different genes interact to make an iris look the way it does.
