Question
If you continue with biological studies in the future, you are most likely going to carry out fruit fly experiments. Drosophila melanogaster are used in genetics labs due to how inexpensive they are, how visible their traits are, and their high reproductive rate.
In Drosophila, the gene for red and white eye colour is found on the X chromosome. The allele for red eyes (XR) is dominant to the allele for white eyes (Xr).
You are asked to cross a pure breeding white-eyed female with a pure breeding red-eyed male.
What are the genotypes of the individuals involved in this cross?
- XRXR
- XRXr
- XRX-
- XrXr
- XRY
- XrY
