在几项实验室研究中发现，雌性对雄性交配尝试的反应存在遗传和表型变异，这表明雌性适应性上的交配成本驱动了性对抗性共同进化。理论模型表明，雌性抗性遗传变异的类型和程度可能会影响性拮抗交配相互作用的进化结果，导致生殖隔离和物种形成或遗传聚类和雌性性多态性的快速发展。然而，在非模式生物的自然种群中这种遗传变异的证据非常有限。同样，我们缺乏对女性生殖力的知识交配的后果和男性交配骚扰的程度在自然环境中。在这里，我们提出了这样的数据从自然种群的颜色多态豆娘。使用一种新的实验技术的彩色除尘男性在该领域，我们表明，遗传的女性颜色变体不同的倾向，接受男性交配尝试。这些变种也不同程度的阻力对男性交配尝试，实现交配的数量和他们的生育力，交配和交配尝试的耐受性。这些结果表明，在自然种群中，可能存在着对雄性交配尝试的抗性和耐受性（交配的适应性后果）的遗传变异，类似于植物病原体抗性系统中的情况。男性交配骚扰可以促进女性性交配多态性的维持，这是由性冲突维持的同域遗传簇的少数经验性例子之一。
Genetic and phenotypic variation in female response towards male mating attempts has been found in several laboratory studies, demonstrating sexually antagonistic co-evolution driven by mating costs on female fitness. Theoretical models suggest that the type and degree of genetic variation in female resistance could affect the evolutionary outcome of sexually antagonistic mating interactions, resulting in either rapid development of reproductive isolation and speciation or genetic clustering and female sexual polymorphisms. However, evidence for genetic variation of this kind in natural populations of non-model organisms is very limited. Likewise, we lack knowledge on female fecundity-consequences of matings and the degree of male mating harassment in natural settings. Here we present such data from natural populations of a colour polymorphic damselfly. Using a novel experimental technique of colour dusting males in the field, we show that heritable female colour morphs differ in their propensity to accept male mating attempts. These morphs also differ in their degree of resistance towards male mating attempts, the number of realized matings and in their fecundity-tolerance to matings and mating attempts. These results show that there may be genetic variation in both resistance and tolerance to male mating attempts (fitness consequences of matings) in natural populations, similar to the situation in plant-pathogen resistance systems. Male mating harassment could promote the maintenance of a sexual mating polymorphism in females, one of few empirical examples of sympatric genetic clusters maintained by sexual conflict.
