Wild-type fruit flies have red eyes. a white-eyed female fly is crossed with a red-eyed male fly. all of the females from the cross are red-eyed and all of the males are white-eyed. what type of inheritance pattern is this?

Sex-linked inheritence

Explanation:

The eye colored gene must be linked in the X Chromosome.

Morgan studied this kind of inheritence, with Drosofila melanogaster.  The first white-eyed fly he found was male, and when this fly was crossed with normal, red-eyed female flies, the F1 offspring were all red-eyed, telling Morgan that the white allele was recessive.

But when the F1 flies were crossed:  All of the female F2 were red-eyed, while about half of the male F2 were white.eyed.
