Question: 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

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 1010 +++ Males 39 +++ 430 32 +yz 27 441 xy+ 31 хуz Total: 2010

Using these data, construct a linkage map of the three genes and calculate the coefficient of coincidence.

Females 1010 +++ Males 39 +++ 430 32 +yz 27 441 xy+ 31 z Total: 2010
