遗传多态性物种为研究遗传变异的维持以及遗传漂变在种群分化中的潜在作用提供了可能性。通过比较中性遗传标记的群体差异与性状频率的群体差异，可以间接推断对多态性状起作用的选择机制。这种方法可以进一步与生态数据相结合，以更好地理解选择主体。在这里，我们推断了作用于昆虫群体中多态交配性状的选择性机制；雌性潜水甲虫的背部结构（粗糙或光滑）。我们最近的工作表明，粗糙的结构具有性对抗功能，可以减少雄性的交配尝试。对于两个物种（Dytiscus lapponicus 和 Graphoderus zonatus），我们不能拒绝将遗传漂变作为种群变形频率差异的解释，而对于第三个物种（Hygrotus impressopunctatus），我们发现不同的选择使种群之间的变形频率分开。此外，H. impresopunctatus 的种群变形频率与当地生物气候因素显着相关，为该物种的当地适应提供了额外的证据。因此，这些数据表明当地生态因素和性冲突在更大的空间尺度上相互作用，从而形成多态性的种群分化。
Genetically polymorphic species offer the possibility to study maintenance of genetic variation and the potential role for genetic drift in population divergence. Indirect inference of the selection regimes operating on polymorphic traits can be achieved by comparing population divergence in neutral genetic markers with population divergence in trait frequencies. Such an approach could further be combined with ecological data to better understand agents of selection. Here, we infer the selective regimes acting on a polymorphic mating trait in an insect group; the dorsal structures (either rough or smooth) of female diving beetles. Our recent work suggests that the rough structures have a sexually antagonistic function in reducing male mating attempts. For two species (Dytiscus lapponicus and Graphoderus zonatus), we could not reject genetic drift as an explanation for population divergence in morph frequencies, whereas for the third (Hygrotus impressopunctatus) we found that divergent selection pulls morph frequencies apart across populations. Furthermore, population morph frequencies in H. impressopunctatus were significantly related to local bioclimatic factors, providing an additional line of evidence for local adaptation in this species. These data, therefore, suggest that local ecological factors and sexual conflict interact over larger spatial scales to shape population divergence in the polymorphism.
