If human eye color brown (B) is dominant to blue (b) and a blue eye man marries brown eye woman, what …?
since blue eyes is recessive then it can only appear as homozygous/pure thus the genotype of the man is bb but the woman has brown eyes which is recessive thus it may appear as either homozygous or heterozygous thus the genotype of the woman is either Bb or BB if the woman is Bb and the man is bb then: 50% children will have blue eyes and 50% children will have brown eyes whereas if the woman is BB and the man is bb then: 100% children will have brown eyes Thus the answer is either 50% or 0%…. depending on the specific genotype of the woman. Hope this helps!
