2012, R. Reinboth, Intersexuality in the Animal Kingdom:monogeny — the production of only male (“arrhenogeny”) or female (“thelygeny”) offspring.
2012, Rigomar Rieger, Glossary of Genetics: Classical and Molecular, page 335: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).
