You are mapping three recessive autosomal linked genes in Drosphila: claret eye, curly wings and fluted  wings. You cross a triple heterozygous female to a homozygous claret, curly, fluted male and count the 1000 offspring with these results. Phenotype observed number fluted 4 claret 173 curled 26 fluted, claret 24 fluted, curled 167 claret, curled 6 fluted, claret, curled 298 wild type 302 Based on the information above (claret, curly, fluted cross) – what is the coefficient of coincidence?

Snail shell coiling is an example of Maternal Effect. Dextral protein (D-) causes right (dextral) coiling of the shell and is dominant to the absence of dextral protein (dd) which causes left (sinistral) coiling.  Martha is a pet snail and she has a sinistral shell.  Answer Questions 6–10.
