    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

      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.
