What progeny ratios are predicted if f1 females are, Ask an Expert

Academics

The recessive allele s causes drosophila to have small wings and the s1 allele causes normal wings. This gene is known to be X linked. If a small-winged male is crossed with a homozygous wild-type female, what ratio of normal to small winged flies can be expectednin each sex in the F1? If F1 flies are intercrossed, what F2 progeny ratios are expected? What progeny ratios are predicted if F1 females are backcrossed with their father?
