Thelygeny

If monogeny is determined exclusively by a cytoplasmic factor, then it is easy to see that the factor will either die out (if it causes arrhenogeny) or will become fixed and thereby sterilize the population (if it causes thelygeny).

Both series of experiments show the possibility of an experimental induction for intersexuality and thelygeny.

monogeny — the production of only male (“arrhenogeny”) or female (“thelygeny”) offspring.
