You discover a new X-linked mutation for antenna shape in Drosophila (fruit flies) which produces long antennae. You call this new allele long (XL2), and discover it is incompletely dominant with the short antennae allele (XL1), so the heterozygotes (XL1XL2) have antennae that are intermediate in length (and XL2 homozygote females have long antennae). Males only have either long or short antennae. You cross a female with long antennae with a male with short antennae. What proportion of their male offspring do you expect to have short antennae?
