[Consequences of experimental triploidy on the fertility and sexual differentiation of a normally amphigonic and diploid lombrician, Eisenia foetida Sav].
The fertility of experimental triploid worms has been studied in Eisenia foetida Sav. This study has led us to the conclusion that the female germ line is abortive while the male germ line may as an exception take part in fertilization. Histological controls have confirmed the differentiating ability of the male line and the break in the development of the female line.
