#SCPH12 I Genetics

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 color. T. H. Morgan crossed black-bodied, normal-winged females and gray-bodied, vestigial-winged males. The F1 were all gray 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?

#SCPH12 I Genetics

Consider two pairs of alleles, G/g and H/h, that follow complete dominance inheritance. The initial cross consisted of GG hh males and gg HH females, and the F I female progeny were test crossed with gg hh males to produce 380 Gghh progeny out of 1000 total progeny. What is approximate distance between Gene G and H.
