Day 21: Dihybrid in Genetics

Dihybrid crossing of alleles is when there are two traits that each parent has. For example in flies there can be a yellow body color that is dominant allele( B) or a black color that is recessive (b) and there can be a red eye color that is dominant (E) and a black eye color that is recessive (e). This picture is the cross of the F1 generation of parents with heterozygous mixes of the body color and eye colors BbEe and BbEe.
