What conditions are likely to apply if the progeny from the cross AaBb × AaBb appear in the 9:3:3:1 ratio? A)gene interaction and independent assortment B)incomplete segregation and complete dominance C)dihybrid cross with incomplete dominance D)complete dominance,independent assortment,and no gene interaction E)dihybrid test cross

The 9:3:3:1 ratio indicates that both genes are segregating independently and exhibiting complete dominance, with no gene interaction taking place. This is indicative of a classic dihybrid cross with independently assorting genes. Incomplete segregation and incomplete dominance would result in different phenotypic ratios, while a dihybrid cross with incomplete dominance would result in a different phenotypic ratio (such as a 1:2:1 ratio). A test cross involves crossing an individual with a dominant phenotype to a homozygous recessive individual, which is not indicated in the given scenario.
