Notes

The ethylmethanesulfonate, acting on larva of the wild strain of Caenorhabditis elegans, allowed us to isolate a recessive mutant, f70, with an abnormal sexual differentiation. Both the gonad and genital tractus which are phenotypically hermaphrodite and functional and the copulatory bursa which is typical of the rare males (1/1,000) usually observed in such a population are found on this self-fertilizing mutant. The mutation threw off the repression of the mitotic division mechanisms in some postembryonic cellular lineages normally blocked in the hermaphrodite wild type.
