The genes for vermillion (v) eyes, sable (s) body color, and forker (f) bristles are on the X-chromosome of Drosophile melanogaster. They map in the order of v, s, f, with 10 map units between v and s and 14 map units between s and f.
Assume that i = 1, and suppose that you cross a homozygous wildtype V S F female to a hemizygous recessive v s f male. You will then self-cross the progeny. What are the possible classes (genotype and gender) of progeny and their expected numbers among 2000 progeny?
