Genes A and B are on different chromosomes. A dihybrid with the genotype AaBb undergoes meiosis. Which of the following depicts a possible genotype in a gamete? Genes A and B are on different chromosomes. A dihybrid with the genotype AaBb undergoes meiosis. Which of the following depicts a possible genotype in a gamete?

A) Aa

B) A

C) Bb

D) B

E) AB

Solution

Since the genotype of the dihybrid is AaBb, the four possible gametes it can form are Ab, AB, ab and aB.

Therefore from the choices given above, E is the correct answer.
