There has been substantial interest of late in using population genetic methods to study sexual conflict, where an allele increases the fitness of one sex at some cost to the other (Mank, 2017). Population genomic scans for sexual conflict offer an important advance given the difficulties of identifying antagonistic alleles from more traditional methods, and could greatly increase our understanding of the extent and loci of sexual conflict. This is particularly true for studies in natural populations, for which obtaining accurate fitness measurements for each sex can be challenging. In this issue of Molecular Ecology, Bissegger, Laurentino, Roesti, and Berner (2019) present a cautionary tale about how to interpret these population genomic data.

性冲突的签名实际上是解决冲突的方法。

近来人们对使用群体遗传学方法研究性冲突产生了浓厚的兴趣，其中等位基因以某种成本增加了一种性别对另一种性别的适应性（Mank，2017）。鉴于难以从更传统的方法中识别拮抗性等位基因，针对性冲突的人群基因组扫描提供了重要的进展，并且可以极大地增进我们对性冲突的程度和位点的了解。对于自然种群中的研究尤其如此，因为要获得每种性别的准确体能测量值可能会很困难。在本期《分子生态学》中，Bissegger，Laurentino，Roesti和Berner（2019）提出了有关如何解释这些种群基因组数据的警示性故事。
