Note: Adaptive alleles were categorized as either standing genetic variation (SGV), introgression (Intro.), or de novo mutations, and were estimated independently for molluscivores and scale‐eaters in a previous study (Richards et al., 2021). Asterisks represent traits that were significant at the p < .1 level in the genome‐wide scan, while crosses show traits that corresponded to the same locations in the alternate lake.
