WebApr 9, 2024 · Conversely, if the parents of AaBb had genotypes aaBB and AAbb, then the arrangement of alleles on the chromosomes of the dihybrid would be aB and Ab. Thus, the genotype of the previous generation can determine which of an individual’s gametes are considered recombinant, and which are considered parental. 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.
