A Bombyx mori mutant named dilute black (bd), which has the multiple alleles bd, bdsw and bdf, each affecting both the larval body color and female fertility, was investigated for the manifestation of these pleiotropic traits by mating experiments with the k40, k42 and k452 strains harboring bd, bdsw and bdf, respectively, in the heterozygous state. It was shown that bd, bdsw and bdf were strong, intermediate and weak, respectively, in the degree of larval body color. On the other hand, bd and bdsw were identical to each other in terms of female sterility, whereas bdf was as fertile as normal. The degree of body color and the female sterility showed a high parallelism with each other. On the basis of these results, we proposed that the bd locus consists of closely linked two domains, one for the larval body color and the other for the female fertility.
