This is a two part question both the math and a written explanation must be included. please answewr a and b
Consider the two X-linked genes, z and w, in Drosophila. The two loci are 30 cM apart and each segregates a dominant allele (z+, w+) and a recessive allele (z, w). For each of the following crosses, predict the offspring’s phenotypic frequencies by sex?
a. Heterozygous female in cis configuration x hemizygous z+w male.
b. Heterozygous female in trans configuration x hemizygous zw male.
Explanation / Answer
recombinant genotypes are z+w/z+w, z+w/Y, zw+/z+w, and zw+/Y.
