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.

The following articles are lists of human Y-chromosome DNA haplogroups found in populations around the world.. Y-DNA haplogroups by ethnic group; Y-DNA haplogroups in populations of Europe
The table below shows the human Y-chromosome DNA haplogroups, based on relevant studies, for various ethnic [dubious – discuss] and other notable groups from Europe.The samples are taken from individuals identified with the ethnic and linguistic designations shown in the first two columns; the third column gives the sample size studied; and the other columns give the percentage for each ...
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.
A parahaplogroup is a term used in genetics to identify a paraphyletic haplogroup.. They are normally described with the name of their parent haplogroup plus an asterisk (for instance: F*, U2*), meaning that it includes all derivates from the parent haplogroup (F or U2 in the examples) except those mentioned elsewhere.
Haplogroup X is also one of the five haplogroups found in the indigenous peoples of the Americas. [ 14 ] (namely, X2a subclade). Although it occurs only at a frequency of about 3% for the total current indigenous population of the Americas, it is a bigger haplogroup in northern North America, where among the Algonquian peoples it comprises up ...
Haplogroup N is a human mitochondrial DNA (mtDNA) clade. A macrohaplogroup, its descendant lineages are distributed across many continents. Like its sibling macrohaplogroup M, macrohaplogroup N is a descendant of the haplogroup L3.
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 mitochondrial phylogenetic tree.
