thelygeny

noun

1. The production of only female offspring.

   uncountable

   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).

Where it comes from

From Ancient Greek θῆλυς (thêlus) + -geny.
