Web23 feb. 2024 · Parthenogenesis is thought to be favored in the short term because it generates a transmission advantage ( 4, 5 ), as well as the advantage of assured reproduction when mates are scarce ( 6, 7 ). The short-term benefits of parthenogenesis, however, are believed to come along with long-term costs.
