A Thirty skin samples were collected along Eastern North Pacific (ENP) locations near Alaska (AK), British Columbia (BC), Washington (WA), Oregon (OR), and California (CA) from 1995 to 2017. Twenty samples were collected in seven sites within the Gulf of California (GOC) from Bahía de La Paz and Los Frailes in the southern Gulf to Bahía de los Ángeles, Puerto Refugio, and Bahía Kino around the Midriff islands (Table S1). B PCA for 50 samples are colored by their location origin. The admixed individuals are labeled. C Admixture analyses supported two ancestral populations (K = 2). The map in A was generated with the R package ggOceanMaps112 which uses publicly available bathymetry data from the ETOPO1 1-arc minute global relief data set distributed by the National Center for Environmental Information113 (https://www.ncei.noaa.gov/products/etopo-global-relief-model). Source data are provided as a Source Data file.
