red beetle with genotype AABB is crossed with a yellow beetle with genotype aabb. The heterozygous F1 beetles are crossed to each other to make the F2 generation. If the beetle color trait is controlled by dominant epistasis of allele B over gene A, what phenotype would you expect for an individual with genotype aaBb?   Group of answer choices 1.red 2.yellow 3.another color, but not red or yellow 4.either red or yellow
