摘要: The Y chromosome is paternally inherited and therefore serves as an evolutionary marker of patrilineal descent. Worldwide DNA variation within the non-recombining portion can be represented a monophyletic phylogenetic tree in which branches (haplogroups) are defined by at least one SNP. Previous human population genetics research has produced wealth knowledge about worldwide distribution Y-SNP haplogroups. Here, we apply previous very recent on phylogeny Y-haplogroup introducing two multiplex genotyping assays that allow for hierarchical detection 28 Y-SNPs defining major PCR amplicons were kept small to make method sensitive thereby applicable limited amount and/or quality such forensic settings. These thus form valuable tool researchers fields genetic anthropology infer man's bio-geographic ancestry from DNA.
