arrhenogeny
The production of only male 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 ἄρρην (árrhēn) + -geny.
