原文开头
Maria Akopyan1,2†*, Arne Jacobs3,4†, Jessica A. Rick3,5, Aryn P. Wilder3,6, Zofia A. Baumann7, David Conover8, Hannes Baumann7, Nina O. Therkildsen3 Chromosomal inversions are often implicated in divergence between distinct ecotypes, but their role in maintaining continuous adaptive divergence in complex traits remains poorly understood. Using quantitative and population genetics, transcriptomics, and artificial selection experiments, we demonstrate how inversions enable clinal adaptive divergence along a steep environmental gradient despite extensive gene flow in a widely distributed marine fish. We show that three inversions are associated with multiple adaptive traits and harbor the strongest signatures of divergent selection in the genome, implying a crucial adaptive role. …
