Number of SNPs, percentage of SNPs and number of SNPs/10 Kbp in the different classes of Y chromosome sequences subdivided for their relative phylogenetic value (Informative, Singleton, and Discarded). Bold numbers refer to the main Y chromosome regions (X-degenerate and non X-degenerate) and to the Total; regular numbers refer to the classes within the non X-degenerate region; italic numbers refer to the sub-regions within the Ampliconic class.
