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 R, or R-M207, is a Y-chromosome DNA haplogroup. 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. Others have long been present, at lower levels, in parts of West Asia and Africa.
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 Haplogroup R is Haplogroup R2 (R-M479).
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.

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 ]
R-L151, also known as R-L11 and R1b1a2a1a, is a human Y-chromosome DNA haplogroup; a subclade of the broader haplogroup R1b (R-M343). [1] It is most often found in males from Western Europe – especially Western France , Northern Spain , Northern Portugal , Great Britain , and Ireland .
Haplogroup R0 derives from the macro-haplogroup R. It is an ancestral clade to the R0a subclade and haplogroup HV , and is therefore antecedent to the haplogroups H and V . R0's greater subclade variety in the Arabian Peninsula suggests that the clade originated in and spread from there.
