模型的进化稳定的策略，旨在确定是否异配双亲性别的缺点是由于男性分配的成本或减数分裂的成本。结果表明：（1）双亲性行为的代价是由于基因共享，因为突变增加了非闭花受精孤雌生殖卵子在共性个体中的比例;（2）双亲性行为的代价是由于雄性分配，因为突变增加了共性个体的体细胞生殖，而突变增加了雌雄异株雌性的部分致病性。一般来说，当增加单亲繁殖的突变影响雄性分配决定之前的事件时，双亲性行为的成本是由于雄性分配造成的，而当增加单亲繁殖的突变影响雄性分配决定之后的事件时，双亲性行为的成本是由于基因共享造成的。
Models of evolutionarily stable strategies are presented, which were designed to determine whether the disadvantage of anisogamous biparental sex is due to the cost of male allocation or to the cost of meiosis. The results show that (1) the cost of biparental sex is due to gene sharing given mutations increasing the proportion of non-cleistogamous parthenogenetic ova in cosexual individuals and (2) the cost of biparental sex is due to male allocation given mutations increasing somatic reproduction in cosexual individuals and mutations increasing partial pathenogenesis in dioecious females. It is suggested that, in general, the cost of biparental sex is due to male allocation when mutations that increase uniparental reproduction affect events before the male-allocation decision, and that the cost of biparental sex is due to gene sharing when mutations that increase uniparental reproduction affect events that come after the male-allocation decision.
