Heliconius melpomene is a species of butterfly with ZW sex determination. H. melpomene's wing spots are normally orange, but a recessive Z-linked mutation causes the spots to be yellow, while a recessive autosomal mutation causes the spots to be red. Butterflies homozygous (or hemizygous) for both mutations have no wing spots. What are the expected F1 and F2 phenotypes from a cross between a red-spotted female and a yellow-spotted male?
