Question

A genetic problem based on mendel laws

blue eye color is caused by a recessive gene. the man has brown eyes and his mother has blue eyes. can a man's father have blue eyes?​

Answer 1

. If B is the allele for brown eyes and b is blue, the genotype of the blue-eyed man is bb. His wife must be a Bb heterozygote--she must have a B allele (she has brown eyes), but she must also have inherited a b allele from her blue-eyed mother (whose genotype was bb).
