A fruit fly with a gray body and red eyes (genotype BbPp) is mated with a fly having a black and purple eyes (genotype bbpp). Show diagrammatically a genetic cross between the two flies and the possible genotypes and phenotypes of F1. What ratio of offspring would you expect if the body-colour and eye-colour genes are on different chromosome (unlinked)? When mating is actually carried out, most of the offspring look like the parents, but 3% have a gray body and purple eyes, and 3% have a black body and red eyes. Compare and discuss the observation with your answer in part (

A fruit fly with a gray body and red eyes (genotype BbPp) is mated with a fly having a black and purple eyes (genotype bbpp).
- Show diagrammatically a genetic cross between the two flies and the possible genotypes and
phenotypes of F1. What ratio of offspring would you expect if the body-colour and eye-colour genes are on different chromosome (unlinked)?
- When mating is actually carried out, most of the offspring look like the parents, but 3% have a gray body and purple eyes, and 3% have a black body and red eyes. Compare and discuss the observation with your answer in part (
