Fig. 1: Distribution of genetic variation among Old World camels.
From: Genomic signatures of domestication in Old World camels
a Summary of the phylogenetic relationships among Old World camels using the alpaca (Vicugna pacos) as an outgroup. b Results from the population clustering analysis. Each horizontal bar corresponds with the proportion of ancestry in either two or three population clusters. c The first two principal components explain 23.3% and 10.1% of the SNP variation, respectively, and easily differentiate the three camel species. d Euler diagram showing the number of segregating SNPs unique to each species and shared between them. Note that the number of C. bactrianus individuals (n = 7) was less than the number of C. ferus and C. dromedarius individuals (n = 9). Approximately 2.1 million SNPs fixed between species are not included.
