In Drosophila, eye color is inherited through the interaction of genes according to the type of complementarity. In this case, the combination of genes A_B_ determines the red color of the eyes, aabb – white, aaB_ – bright red, A_bb – brown. What color of eyes will the offspring obtained from crossing a heterozygous red-eyed fly with a heterozygous fly with bright red eyes have?

Offspring obtained from crossing a heterozygous red-eyed fly with a heterozygous fly with bright red eyes will have red, bright red, brown and white eyes in a ratio of 3: 3: 1: 1.
