Genome-wide population structure of scabies mites across diverse hosts

Caption

Population structure of Sarcoptes scabiei inferred from genome-wide nuclear single-nucleotide polymorphism (SNP) data. (A) ADMIXTURE analysis showing estimated ancestry proportions for 83 quality-filtered sample-level datasets from diverse host species, assigned to seven ancestry clusters (K1–K7). (B) Principal component analysis (PCA) of genome-wide SNP data. Each point represents one sample-level dataset and is coloured according to its ADMIXTURE cluster assignment. (C) Phylogenetic relationships inferred from high-quality, linkage-pruned nuclear SNPs. Each bar in panel A represents one dataset derived from an individual mite or a pool of mites. Colours indicate estimated ancestry proportions, not transmission routes.
