Fig. 3: Genetic structure based on haplotype-sharing pattern.

A PCA based on haplotype sharing. The chunkcount coancestry matrix obtained with the ChromoPainter was used to perform PCA analysis with prcomp in R. The first and third components are shown in the scatterplot. B The refined fineSTRUCTURE tree consisted of 40 homogeneous clusters. Clusters containing more than two Kuwaiti individuals are presented in various colors, as shown in the legend.
