A female fruit fly with no wing bristles was mated to a male fruit fly with dark eyes and no thoracic bristles. Their wild-type female offspring were then mated to males homozygous for the mutations. The resulting progeny showed frequencies of the traits that could be used to determine the gene order and genetic distances between genes on the chromosome.

1. please help! thank you!
In the fruit fly, Drosophila, a spineless (no wing bristles, s+ ) female fly is mated to a male that is
claret (dark eyes, c vs. + ) and hairless (no thoracic bristles, h vs. + ). Phenotypically wild-type
F1female progeny were mated to fully homozygous (mutant) males, and the following progeny (
1000 total) were observed: 1. Give the gene order 2. Calculate frequencies of SCOs 3. Draw a
