Phylogenetic network of the 1,194 samples. Median Joining network of the 1,194 Y chromosome sequences. The haplogroups are labelled according to the most recent ISOGG nomenclature. a) The main known marker is in red. The number of SNPs of each branch is in blue. b) The number of SNPs of each branch belonging to the X-degenerate class is in green. The number of SNPs of each branch belonging to the classes other than X-degenerate is in dark red.
