Using these data, construct a
linkage map of the three genes
Assume that in Drosophila there are three genes x, y, and z, with each mutant allele recessive to the wild-type allele. A cross between females heterozygous for these three loci and wild-type males yielded the following progeny: Females Males 39 430 32 27 +y z xyz 31 Total: 2010
