In Drosophila the genes for wing size (phenotypes normal or vestigial) and bristle length (phenotypes long or short) are inherited independently. The following crosses are made, showing only the phenotypes.

Progeny!

Parental crosses
A normal, long x vestigial, long
B normal, long x vestigial, long
C normal, long x normal, short
D normal, long x vestigial, short
E normal, long x normal, long
