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. [4] Haplogroup R is a descendant of the macro-haplogroup N.
As haplogroups were named in the order of their discovery, the alphabetical ordering does not have any meaning in terms of actual genetic relationships. The hypothetical woman at the root of all these groups (meaning just the mitochondrial DNA haplogroups) is the matrilineal most recent common ancestor (MRCA) for all currently living humans.
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.
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.

R-M343 (previously called Hg1 [citation needed] and Eu18 [citation needed]) is the most frequent Y-chromosome haplogroup in Europe. It is an offshoot of R-M173, characterised by the M343 marker. [25] An overwhelming majority of members of R-M343 are classified as R-P25 (defined by the P25 marker), the remainder as R-M343*.

R-Z17 is a subclade of the R-U106 branch of the human Y-chromosome haplogroup named Haplogroup R, associated with the single nucleotide polymorphism (SNP) designated Z17. R-Z17 likely branched off from its parent clade, R-Z18 , around 2150 BCE, with a range of 2805 BCE to 1607 BCE.
