Janet is performing a test cross to determine the linkage relationships between three Drosophila genes, dpy, unc and dor. Her entire grade depends on getting this right! She testcrosses females heterozygous for the recessive alleles:

(a) What is the genotype of the
heterozygous female?
(b) Construct a map of the region indicating the order of the genes and the distances (in map units) between them.
(c) What is the interference in this region?
