Haplogroup R1b (R-M343), previously known as Hg1 and Eu18, is a human Y-chromosome haplogroup.. It is the most frequently occurring paternal lineage in Western Europe, as well as some parts of Russia (e.g. the Bashkirs) and across the Sahel in Central Africa, namely: Cameroon, Chad, Guinea, Mauritania, Mali, Niger, Nigeria and Senegal (concentrated in parts of Chad with concentration in the ...
Haplogroup R-M269 is the sub-clade of human Y-chromosome haplogroup R1b that is defined by the SNP marker M269. According to ISOGG 2020 it is phylogenetically classified as R1b1a1b . It underwent intensive research and was previously classified as R1b1a2 (2003 to 2005), R1b1c (2005 to 2008), R1b1b2 (2008 to 2011) and R1b1a1a2 (2011 to 2020).
The proposed candidates include haplogroup C3, haplogroup Q, haplogroup R1b and haplogroup C2. [ 50 ] Y chromosome haplogroup C2c1a1a1-M407 is carried by Mongol descendants of the Northern Yuan ruler from 1474–1517, Dayan Khan , who is a male line descendant of Genghis Khan which was found out after geneticists in Mongolia conducted tests on ...
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non-recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share similar numbers of short tandem repeats (STRs) and single-nucleotide polymorphisms (SNPs). [ 2 ]
In human population genetics, Y-Chromosome haplogroups define the major lineages of direct paternal (male) lines back to a shared common ancestor in Africa. Men in the same haplogroup share a set of differences, or markers, on their Y-Chromosome, which distinguish them from men in other haplogroups.
