Polygenic Selection within a Single Generation Leads to Subtle Divergence among Ecological NichesINc.

Genome biology and evolution - 3 Feb 2021

Ehrlich Moritz A, Wagner Dominique N, Oleksiak Marjorie F, Crawford Douglas L

Abstract excerpt

Selection on standing genetic variation may be effective enough to allow for adaptation to distinct niche environments within a single generation. Minor allele frequency changes at multiple, redundant loci of small effect can produce remarkable phenotypic shifts. Yet, demonstrating rapid adaptation via polygenic selection in the wild remains challenging. Here we harness natural replicate populations that...
