In Drоsоphilа, yellоw bodies (y ) аnd white eyes (w ) аre both caused by recessive X-linked alleles. The normal alleles (y+ amd w+ ) cause tan bodies and red eyes, respectively. A y w female is mated to a y+ w+ male and the F1 progeny are allowed to mate with each other. Two hundred F2 were observed and they are: 55 y w; 45 y w+; 45 y+ w; 55 y+ w+.
