You have identified several recessive mutations on a chromosome. These mutations include eyeless, Dpy-1 and hairy. You have a female worm that is heterozygous for eyeless, hairy, and dpy-1 and testcross the animal (i.e., mate the het to an animal homozygous for eyeless, hairy, dpy-1. Among the 1000 F1 progeny from the testcross, the following phenotypes were observed: Dpy-1, eyeless, hairy 450 wild type 470 hairy, dpy-1 40 eyeless 40 eyeless, hairy 34 dpy-1 36 eyeless, dpy-1 4 hairy 6 a) What gene is in the middle? b) What is the order of genes on the chromosome and the map distances between the genes? c) Calculate the interference?
