Which of the following phenotypic ratios would be expected to result from a dihybrid cross?

Question

Quizplus · Accepted Answer

A dihybrid cross involves two traits that are being studied simultaneously, and each trait has two alleles. When the alleles of the two traits sort independently into gametes during meiosis, a 9:3:3:1 ratio of phenotypes is expected in the offspring. This means that for every 16 offspring, 9 will display both dominant traits, 3 will display one dominant and one recessive trait, 3 will display the other dominant and recessive trait, and 1 will display both recessive traits. Therefore, the correct answer is B.
