Correlation plots of the ancestry proportions at k = 4 in the ADMIXTURE analysis comparing autosomes and X-chromosome SNPs.
<p>North African, sub-Saharan, Middle Eastern, and European ancestry proportions are shown in different plots. Solid black lines represent linear correlations between autosomal and X-chromosome components.</p
Geographic location of the Algerian samples genotyped in the present study (in red) and the samples obtained from the literature (in yellow).

Y-chromosome population structure.
<p>A) Principal component analysis of haplogroups frequencies. B) Multidimensional scaling plot based on R<sub>ST</sub> distances between populations derived from Y-STR data.</p
Genome-wide population structure.
<p>A) Principal component analysis of ∼44,000 SNPs showing the top two components. B) Maximum likelihood tree showing populations relationships.</p
Frequency of the major Y-chromosome haplogroups in North Africa and surrounding regions.
<p>Intensity of the colors reflects the frequency of a haplogroup in the studied populations. A) Location of the analyzed populations. B–F) Frequency distribution of haplogroups E-M81, E-M78, E-M123, J-M267, and J-M172 respectively.</p
