摘要: Background: A gynogenetic species is a hybrid in which females must mate with males of their parental to initiate egg development, but inheritance strictly maternal. Question: Is the mating preference an all-female, fish and its repeatable? Organisms: The Amazon molly, Poecilia formosa, livebearing origin. Its are P. latipinna (paternal) mexicana (maternal). Methods: We examined compared repeatability preferences formosa female for larger vs. smaller males. also large male mexicana. Repeatability relates variation within individuals between individuals. related measures consistency individual examine whether were unanimous. Conclusions: Females all three showed population-level mean was low mollies even though they clonal species. maternal species, mexicana, high males, not
