Environmental heterogeneity generates opposite gene-by-environment interactions for two fitness-related traits within a population.

Evolution; international journal of organic evolution - 1 Feb 2015

Culumber Zachary W, Schumer Molly, Monks Scott, Tobler Michael

Abstract excerpt

Theory predicts that environmental heterogeneity offers a potential solution to the maintenance of genetic variation within populations, but empirical evidence remains sparse. The live-bearing fish Xiphophorus variatus exhibits polymorphism at a single locus, with different alleles resulting in up to five distinct melanistic "tailspot" patterns within populations. We investigated the effects of heterogeneity in...
