A brown-eyed man marries a blue-eyed woman and they have eight children, all with brown eyes. Can you be sure whether the man is homozygous or heterozygous for eye color?

  • genetics -

    If heterozygous, the probability of all 8 getting the dominant gene by chance = .5^8 = .004

    Although I cannot be absolutely sure, I would reject the heterozygous hypothesis at the P ≤ .01 Level.
