A fly was found that had two mutations, Q&Z.Reciprocal crosses between wild type flies and Q&Z mutants gaveall Q&Z mutant F1 progeny in all cases. These results suggestthat the Q&Z mutations have an autosomal dominant inheritancepattern. The genes X, Q, and Z appear to be linked. To map thegenes the following crosses were done. A homozygous Q, Z mutantfemale was crossed to a homozygous X mutant males shown in thediagram below. X, Q, Z mutant females from the F1 generation werethen crossed to homozygous, wildtype males. X, Q, and Z aredominant mutations. There were 8 different types of F2 progenyproduced from this cross as listed in the table below. Using thisinformation and that given above provide the information requestedbelow.

1st complete the cross diagram below for thiscross showing the complete genotypes for all of the flies, usingstandard conventions.
