2012, Rigomar Rieger, Glossary of Genetics: Classical and Molecular, page 3352 more examples
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).
1982, Graham Bell, The Masterpiece of Nature :: The Evolution and Genetics of Sexuality, page 441Both series of experiments show the possibility of an experimental induction for intersexuality and thelygeny.
