In Drosophila Melanogaster, Vestigial Wings Are Determined by a Recessive

In Drosophila melanogaster, vestigial wings are determined by a recessive allele of a gene that is linked to a gene with a recessive allele that determines black body colour. Thomas H Morgan (1907) crossed black-bodied, normal-winged females and grey-bodied, vestigial-winged males. The F1 were all grey bodied, normal winged. The F1 females were crossed to homozygous recessive males to produce testcross progeny. Morgan calculated the map distance to be 17 map units. Which of the following information is correct about the testcross progeny?

A) black-bodied, normal-winged flies = 17% of the total
B) black-bodied, normal-winged flies plus grey-bodied, vestigial-winged flies = 17% of the total
C) grey-bodied, normal-winged flies plus black-bodied, vestigial-winged flies = 17% of the total
D) black-bodied, vestigial-winged flies = 17% of the total
