Extended Data Fig. 2: Migration distance correlates with an estimate of heterozygosity from higher-coverage samples.

Each point represents one species (N = 27) and points are colored by migration distance, as in main text figures, where non-migrants are shown in gray. This plot shows heterozygosity estimated by ANGSD from reference-mapped genomes. The intercept and slope of the line were estimated with a phylogenetic generalized least squares (PGLS) model.
