The recessive alleles for yellow body (yb) and cut wings (cw) identify two autosomal genes on the second chromosome of drosophila melanogaster. when females, heterozygous at these two genes (yb+yb cw+cw), were crossed with yellow-bodied, cut-winged males, the following classes and numbers of progeny (out of 1000) were obtained:
a. wild type body color, wild type wings 120
b. wild type body color, cut wings 360
