Quizplus · Accepted Answer

In a dihybrid cross between Aa Bb and aa Bb, the potential phenotypes are determined by the combinations of dominant and recessive alleles. The possible phenotypes are: dominant for both traits, dominant for the first and recessive for the second, recessive for the first and dominant for the second, and recessive for both traits. Thus, there are 4 unique phenotypes.
