In flies, red eyes (R) are dominant to brown eyes (r) and brown bodies (B) are dominant to yellow bodies (b).

A fly with genotype R r B b is mated with a fly with genotype r r b b. What percentage of offspring will have red eyes and yellow bodies?

From the result of crossing RrBb with rrbb (see the attached Punnet's square), the genotypic ratio of the offspring along with their respective phenotypic ratio is:

RrBb - red eyes, brown body - 1/4
Rrbb - red eyes, yellow body - 1/4
rrBb - brown eyes, brown body - 1/4
rrbb - brown eyes, yellow body - 1/4

Thus, the proportion of the offspring with red eyes and yellow bodies is 1/4 or 25%
