The progeny of a Drosophila female (heterozygous at three loci, y+y, ct+ct, w+w) crossed to a wild type male are listed as follows:

Females        y+ ct+ w+     2000

Males            y+ ct+ w        773

                       y  ct  w+        782

                       y  ct+  w+      201

                      y+ ct   w        209

                      y+ ct  w+        15

                      y  ct+ w          16

                      y  ct  w            3

                      y+ ct+ w+       1
