Question

The number of classes of phenotypes in the f2 generation of a cross between dihybrids involving both the genes with incomplete dominance would be

Answer 1

A dihybrid cross tracks two traits. Both parents are heterozygous, and one allele for each trait exhibits complete dominance *. This means that both parents have recessive alleles, but exhibit the dominant phenotype. The phenotype ratio predicted for dihybrid cross is 9:3:3:1.
