What phenotypic cleavage can be expected when crossing diheterozygotes?
| February 14, 2021 | education
When crossing diheterozygotes, a 9: 3: 3: 1 phenotype splitting should be expected.
Example: let’s take the AaBb digheterozygotes.
When crossing the parents of the digheterozygotes AaBb, we get the following distribution of the genotype variants of the offspring: AABB: 2 AaBB: aaBB: 2 AABb: 4 AaBb: 2 aaBb: AAbb: 2 Aabb: aabb. It corresponds to a 9: 3: 3: 1 phenotype cleavage.
