In Drosophila flies, the allele b gives a black body, and the allele b+ gives brown, the wild-type
phenotype. The allele wx of a separate gene gives waxy wings, and wx+ gives non-waxy. The allele cn of
a third gene gives cinnabar eyes, and cn+ gives red. A female heterozygous for these three genes is
testcrossed, and 745 progenies are produced which are
