When you perform a dihybrid cross with 2 heterozygous individuals for the 2 traits, what is the expected phenotypic ratio?

9:3:3:1

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.
