FIGURE 3. Genetic variation among dingoes, New Guinea singing dogs, wolves and modern domestic dogs based on genomewide single-nucleotide polymorphism (SNP) data expressed using principal components analysis (PCA) representing 841 dogs (green), 24 dingoes (black), 5 New Guinea singing dogs (orange), 14 wolves (blue). Within the dogs there were 292 breed dogs (light green) and 549 village dogs (dark green). We genotyped each of these canid samples using the Illumina CanineHD 170 SNP chip (data from Cairns 2015 and Shannon et al. 2015). We analysed genotype data in PLINK 1.9 (Chang et al. 2015) by merging the datasets and removing SNPs that were missing in more than 10% of samples. The total remaining SNP markers were 166,019. We did the PCA in PLINK 1.9 and visualised the results using R (v 3.2.1). PC1 accounts for 49.2% of variation,
