We crossed a red-eyed gray Drosophila, heterozygous for two alleles, with a red-eyed black Drosophila

We crossed a red-eyed gray Drosophila, heterozygous for two alleles, with a red-eyed black Drosophila, heterozygous for the first allele. Red eyes and gray body are dominant signs, cherry eyes and black body are recessive signs. Determine the genotypes of the parents, gametes, the numerical segregation of the offspring by phenotype and genotype.

A – red eye color (dominant gene)
a – cherry eye color (recessive gene)
B – gray body (dominant gene)
b – black body (recessive gene)

Parental genotypes: AaBb – phenotypically with red eyes and gray body, heterozygous for both alleles, Aabb – phenotypically with red eyes and black body, heterozygous for the first allele
Gametes: first parent (AaBb) – AB, Ab, aB, ab; second parent (Aabb): Ab, ab.
Distribution by genotype: AaBb (2): Aabb (2): AABb (1): AAbb (1): aaBb (1): aabb (1)
Distribution by phenotype: 3: 3: 1: 1 – A_B_ (3): A_bb (3): aaBb (1): aabb (1)
Red eyes, gray body – 35%
Red eyes, black body – 35%
Cherry eyes, gray body – 15%
Cherry eyes, black body – 15%
