(a) PCA for individuals in Sockeye Lake, Kathleen Lake, Frederick Lake, and the Whitehorse Rapids Fish Hatchery (neutral, 271 SNPs) (PC1 = 12.5%, PC2 = 3.7%, genetic variation explained), showing a clear separation of Frederick Lake individuals and a partial separation of hatchery individuals from KNPR individuals. (b) PCA for individuals in Sockeye and Kathleen Lakes (neutral, 271 SNPs) (PC1 = 2.9%, PC2 = 2.7%, genetic variation explained) revealing no clear clustering by year or location.
