配偶的亲缘关系会对适应性产生影响，避免近亲繁殖是形成交配行为的一个潜在因素。当女性无法避免与亲属交配，他们可能会利用postcopulatory机制作为一种替代手段，以避免近亲繁殖。如果雌性在乱伦交配后增加了再交配的倾向，它们就可以减少近亲生下后代的可能性。本文研究了赤豆象雄性亲缘关系对雌性首次交配和再交配概率的影响。女性没有表现出precopulatory歧视兄弟在他们的第一次或第二次交配。与此相反，女性交配第一次与兄弟更愿意重新交配比女性交配第一次无关的男性。我们没有发现任何证据表明雄性在与姐妹篇交配时转移较少的精子。本研究表明，中华绒螯蟹在交配前和交配过程中并不避免近亲繁殖。相反，与相关雄性交配的雌性适应了随后的交配行为，以避免近亲繁殖的潜在成本。在这个物种中，一妻多夫制可能是雌性试图通过与亲戚交配后再交配来防止遗传不相容的结果。
Mate relatedness can have an impact on fitness and inbreeding avoidance is a potential factor shaping mating behaviour. When females are unable to avoid mating with kin, they may exploit postcopulatory mechanisms as an alternative means to avoid inbreeding. If females increase their remating propensity after incestuous matings, they could reduce the likelihood of kin siring their offspring. We investigated the effects of male relatedness on the probabilities of female first mating and remating in the adzuki bean beetle, Callosobruchus chinensis. Females showed no precopulatory discrimination against brothers at their first or second mating. In contrast, females mated first with brothers were more willing to remate than females mated first with unrelated males. We found no evidence that males transfer fewer sperm when mating with sisters. This study suggests that C. chinensis does not avoid inbreeding before and during copulation. Instead, females that mated with related males adapted their subsequent mating behaviour to avoid the potential costs of inbreeding. Polyandry in this species may be the result of females attempting to prevent genetic incompatibility by remating after having mated to a relative.
