A cross was made to produce D. melanogaster flies
heterozygous for two pairs of alleles: A and a, which
determine long versus short wings, and B and b, which
determine gray versus ebony body color. The following F2
data were obtained:
Long wing, gray body 240
Long wing, ebony body 40
Short wing, gray body 40
Short wing, ebony body 80
Test these data for agreement with the 9 : 3 : 3 : 1 ratio
expected if the two pairs of alleles segregate independently,
if not calculate the linkage percentage for these two genes.
