Question

Quizplus · Accepted Answer

The usual phenotypic ratio of a dihybrid cross is 9:3:3:1, meaning the offspring can have four different phenotypes in the ratio of 9 (dominant phenotype for both traits):3 (dominant phenotype for one trait and recessive for the other):3 (recessive phenotype for one trait and dominant for the other):1 (recessive phenotype for both traits). This ratio results from the random assortment of two different traits during meiosis and the independent segregation of their alleles.
