Question

although there are 16 squares in dihybrid cross how many different genotypes and phenotypes are formed ?

Answer 1

There are four different phenotype in a dihybrid cross which are in the ratio 9:3:3:1.And genotype ratio is a very complex ratio in dihybrid cross

Answer 2

A dihybrid cross shows the inheritance of two through two generations.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.
