Assume that a dihybrid cross AaBb × AaBb is made in which the gene loci are autosomal,independently assorting,and incompletely dominant.What phenotypic ratio would you expect from such a cross? A)1:2:1:2:4:2:1:2:1 B)1:2:2:1:4:2:1:2:1 C)2:1:1:2:2:1:4:2:2 D)2:2:2:2:2:2:2:2 E)1:2:1:2:2:2:1:4:1

In a dihybrid cross involving genes that are independently assorting and show incomplete dominance, each trait will have a 1:2:1 phenotypic ratio (reflecting the incomplete dominance), and when combined for two traits, this results in a 1:2:1:2:4:2:1:2:1 overall phenotypic ratio. This is because each trait combination follows the basic Mendelian inheritance pattern, but with incomplete dominance, the heterozygous phenotype is distinct, leading to more phenotype categories.
