Haplogroup R1, or R-M173, is a Y-chromosome DNA haplogroup. A primary subclade of Haplogroup R (R-M207), it is defined by the SNP M173. The other primary subclade of ...
In this system, names with the format "R1" and "R1a" are "phylogenetic" names, aimed at marking positions in a family tree. Names of SNP mutations can also be used to name clades or haplogroups. For example, as M173 is currently the defining mutation of R1, R1 is also R-M173, a "mutational" clade name. When a new branching in a tree is ...
Haplogroup R, or R-M207, is a Y-chromosome DNA haplogroup. It is both numerous and widespread among modern populations. It is both numerous and widespread among modern populations. Some descendant subclades have been found since pre-history in Europe , Central Asia and South Asia .
Haplogroup R is a widely distributed human mitochondrial DNA (mtDNA) haplogroup. Haplogroup R is associated with the peopling of Eurasia after about 70,000 years ago, and is distributed in modern populations throughout the world outside of sub-Saharan Africa .
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 ...
Its subclade R1b1a2 (M269) is the haplogroup that is most commonly found among modern Western European populations, and has been associated with the Italo-Celtic and Germanic peoples. Haplogroup R1 (M173) Found throughout western Eurasia. Haplogroup R1a (M420) Found in Central Asia, South Asia, and Central, Northern and Eastern Europe, Balkans
A haplotype is a group of alleles in an organism that are inherited together from a single parent, [1] [2] and a haplogroup (haploid from the Greek: ἁπλοῦς, haploûs, "onefold, simple" and English: group) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. [3]
Haplogroup R is the most observed Y-chromosome DNA haplogroup among the populations of South Asia, [4] followed by H, L, and J, in the listed order. [4] These four haplogroups together constitute nearly 80% of all male Y-chromosome DNA haplogroups found in various populations of the region. [4]
