(1) They have unisexual flowers, are wind-pollinated, and apparently have a very short and inconspicuous flowering time so that the presence of flowers is easily overlooked.(2) When H. frenatus arrives on an island, the population of the unisexual species plummets.(3) As is the condition in other unisexual vertebrates, the silver crucian carp probably has a hybridization origin.(4) Sexually the species are structurally gynodioecious, but there is a strong tendency towards dioecism with apparently bisexual flowers often being functionally unisexual .(5) Various species may be unisexual , hermaphroditic, or have separate sexes.(6) The genera of Atripliceae, as the tribe is traditionally defined, have flowers that are usually unisexual and enclosed by well-developed bracteoles.(7) The genus has reduced unisexual flowers grouped into characteristic pseudanthia called cyathia.(8) This means that the unisexual females are actually parasitizing bisexual males of these other species.(9) Plants are characterized as having unisexual flowers and dichotomously forked leaves arranged in crowded whorls.(10) Both individuals and gametes were unisexual , and self-fertilization was allowed.(11) A major emphasis has been to evaluate the functional significance of interspecific hybridization, unisexuality and polyploidy in the evolutionary biology of these unusual fish.(12) There are also ‘alternative mating systems,’ which include alternative male strategies, hermaphroditism, and unisexuality .(13) Not all species have been fully investigated, but Millener has estimated that about 25% exhibit unisexuality in New Zealand compared with only 8% in the British flora.(14) Rather than being a viewpoint in support of homosexuality, it's more like an argument favoring an androgynous unisexuality that even most gender benders would find unreflective of their lives.(15) It is likely that he achieved just the effect he was after here, as audiences are forced to confront in full force not homosexuality but unisexuality .(16) Thus, whereas the parental species reproduce sexually, the hybrid reproduces unisexually due to the result of meiotic drive, but still depends on a sexual hang-up.
