摘要

Audet 等人（2024 年）研究了黑腹果蝇在性不和谐的体型选择下发生性冲突的基因组基础。他们报告了性二态性和多变量异型性的有趣形态变化。虽然他们没有发现任何基因变异单独对这些性状有强烈的影响，正如对体型这样的多基因性状所预期的那样，但他们确实发现 3L 染色体上的一个区域显示出性不和谐选择的迹象（即雄性和雌性之间的冲突）。这项研究强调了参与性冲突的潜在基因组区域，为了解性别特异性适应提供了线索。

Digest: Evaluating sexual conflict in the genome.

Audet et al. (2024) investigate the genomic basis of sexual conflict in response to sexually discordant size selection in Drosophila melanogaster. They report interesting morphological changes in sexual dimorphism and multivariate allometry. Although they do not find any genetic variants that individually show a strong effect on these traits, as expected for a polygenic trait such as body size, they do find a region on chromosome 3L showing signs of sexually discordant selection (i.e., conflict between males and females). This study highlights potential genomic regions involved in sexual conflict, offering insights into sex-specific adaptations.
