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 R1b is the dominant haplogroup of Western Europe and is also found sparsely distributed among various peoples of Asia and Africa. 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.

DNA molecule 1 differs from DNA molecule 2 at a single base-pair location (a C/A polymorphism). A haplotype (haploid genotype) is a group of alleles in an organism that are inherited together from a single parent. [1] [2] Many organisms contain genetic material which is inherited from two parents.
Haplogroup L3 is a human mitochondrial DNA (mtDNA) haplogroup. The clade has played a pivotal role in the early dispersal of anatomically modern humans . It is strongly associated with the out-of-Africa migration of modern humans of about 70–50,000 years ago.
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.

In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA. Haplogroups are used to represent the major branch points on the ...
The emergence of haplogroup L1-6 by definition dates a later time, at an estimated 200–130 kya, [1] possibly in a population in eastern Africa. [3] Haplogroup L0 emerges from the basal haplogroup L1-6* somewhat later, at an estimated 190–110 kya. The deep time depth of these lineages entails that substructure of this haplogroup within ...
