Wild-type fruit flies, D. melanogaster, have dark red eyes. Recessive mutations in the X-linked white gene result in white eyes. In the crosses shown below, what fraction of F2 female and male progeny would have red eyes and what fraction would have white eyes? P0 females are homozygous.
Cross 1 P0 white-eyed ? x red-eyed ?
Cross 2 P0 red-eyed ? x white-eyed ?
