Background Next-Generation Sequencing methods have led to a great increase in phylogenetically useful markers within the male specific portion of the Y chromosome, but previous studies have limited themselves to the study of the X-degenerate regions. Methods DNA was extracted from peripheral blood samples of adult males whose paternal grandfathers were born in Sardinia. The DNA samples were sequenced, genotyped and subsequently analysed for variant calling for approximately 23.1 Mbp of the Y chromosome. A phylogenetic tree was built using Network 4.6 software. Results From low coverage whole genome sequencing of 1,194 Sardinian males, we extracted 20,155 phylogenetically informative single nucleotide polymorphisms from the whole euchromatic region, including the X-degenerate, X-transposed, and Ampliconic regions, along with variants in other unclassified chromosome intervals and in the readable sequences of the heterochromatic region. Conclusions The non X-degenerate classes contain a significant portion of the phylogenetic variation of the whole chromosome and their inclusion in the analysis, almost doubling the number of informative polymorphisms, refining the known molecular phylogeny of the human Y chromosome. |
