The problem presents a dihybrid cross involving two genes, G and B, with two alleles each (G/g and B/b). In a dihybrid cross, each gene segregates independently, so the offspring genotype is formed by combining one gamete from each parent, where gametes can be GB, Gb, gB, or gb each with equal likelihood. Option A: GgBb This genotype is heterozygous at both loci (one G and one g, one B and one b). It is a valid possible outcome of a dihybrid cross, because one chromosome f......Login to view full explanation
