Two gene loci, A and B, assort independently, and alleles A and B are dominant over alleles a and b. What is the probability of producing an ABphenotype from a cross AaBb × AaBb?

Respuesta :

Answer:

The correct answer is - 9 out of 16.

Explanation:

It is common case of the dihybrid cross where independent assortment takes pace. In the case of the given cross the genotype and produced gametes from AaBb:

AB, Ab, aB, ab.

From these gametes cross with similar that are produced following genotypes are will form phenotypes in the 9:3:3:1 where the dominant gene is present in the 9 out of 16 offspring.

Thus, the correct answer is - 9 out of 16.
