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
