Problem

Genes D and F are located on separate arms of chromosome 7, with gene D close to the telomere of the p-arm and gene F close to the telomere of the q-arm. The genotypes of Priya and Sasha are:

a) Priya: D1 E2 F1/D2 E1 F2
b) Sasha: D1 E1 F1/D2 E2 F2

Who is more likely to produce gametes with genotype D1 and F2? Explain why
