In the dihybrid cross AaBb *aabb, what proportion of individuals are expected to be homozygotic for both genes in the F₁ generation? A)1/4 B)1/2 C)3/4 D)All are homozygotes. E)None are homozygotes.

Question

Quizplus · Accepted Answer

In a dihybrid cross, the homozygous dominant individuals for both genes are represented as AABB. In the F1 generation of the cross AaBb * aabb, the probability of obtaining AABB individuals is 1/4. This is because the probability of obtaining AA individuals is 1/2, and the probability of obtaining BB individuals is also 1/2. Therefore, the probability of obtaining AABB individuals is (1/2) * (1/2) = 1/4.
