Figure 3

(a) A phylogeny for Betula species, estimated from SNPs in neutrally evolving sites and noncoding sites 2 kb upstream and downstream of genes. Fin, Finland; Sco, Scotland. (b) PCA plot of 60 B. pendula individuals with low levels of admixture and known location information. Individuals diverging along PC2 are all from Punkaharju, Finland, indicating possible admixture from unknown source populations. (c) Heat maps for three-population F3 test statistics. Introgression is significant if the false discovery rate–adjusted Z-score (Z.adj; see Supplementary Note) is significantly negative (adjusted Z-score < − 1.96, purple).
