WebGenotype of Parent 1 (blue eyes) and Parent 2 (brown eyes). As you can see there is a 50% chance that the homozygous recessive trait of blue eyes will be shown on their next kid, a 50% chance that the heterozygous dominant trait of brown eyes is given on the next offspring, and a 0% chance of a homozygous dominant trait given to the offspring. WebHow do you determine genotypes of parents? To construct a Punnett square, the genotypes of both parents must be known. One parent’s alleles are listed across the top of the table, and the other parent’s alleles are listed down the left hand side.
