Eye colour percentages around the world - Lemmy.World

Fun fact: the brown-eyed percentage (70-79%) seems to approximately fit the following genetics rule:

+ A a A AA Aa a Aa aa

AA = 25% aa = 25% Aa = 50%

50% of Aa + 25% of either aa or AA = 75% probability

Punitt squares, haven’t missed those.
That is accurate assuming that eye color is defined by only 2 genes, but in actuality it’s more, possibly as many as 50 different genes.
