摘要

相对较少的研究评估了遗传渗入对与适应性相关的性状的影响。Leitwein等人（2025）利用在西地中海发现的由大西洋和地中海种群杂交而成的欧洲鲈鱼混合种群解决了这个关键问题。他们发现，大西洋血统比例较高的鱼类表现出与适应性降低相关的表型，这表明在这种情况下，基因渗入是不利的。

Digest: Survival of the fittest in an admixed seabass population.

Relatively few studies have assessed the impacts of introgression on traits associated with fitness. Leitwein et al. (2025) address this key question using an admixed population of European seabass found in the Western Mediterranean that results from hybridization between Atlantic and Mediterranean populations. They find that fish with a higher ratio of Atlantic ancestry exhibit phenotypes associated with reduced fitness, demonstrating that introgression in this case is disadvantageous.
