Question

how to calculate phenotypic and genotypic ratio of dihybrid cross

Answer 1

Explanation:

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.

Answer 2

Answer:

p ratio -9:3:3:1

g ratio-2:1:1:1:1:2:2:4:2
