Principal component analysis (PCA) plots of LG2 and LG7 in Ammarnäs (2013 samples), with phased male haplotypes. For both linkage groups, the Y haplotypes (blue triangles) cluster apart from male X haplotypes (green squares), the latter clustering together with female genotypes (pink circles). The Y outlier is male A17M. LG2 plot updated from Rodrigues et al. (2015).
