Answer 1

Explanation:

The eye colour in Drosophila is sex linked and allele is present on X chromosome. Thus a red eyed heterozygous female (XR Xr) will produce two types of gametes XR and Xr while the white eyed male (Xr Y) will produce two gametes ie Xr and Y. The R allele codes for red eye colour and r allele codes for white eye colour. Y chromosome does not has any allele for eye colour and R is dominant over r.

Possible combinations of these four gamete types are

XR Xr ie Red eye female,

XR Y ie Red eye male,

Xr Xr ie white eye female,

Xr Y ie white eye male.
