The following articles are lists of human Y-chromosome DNA haplogroups found in populations around the world. Y-DNA haplogroups by ethnic group;
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.

(b) Counts of haplogroups in table format. For populations details, see 1000 Genomes Project#Human genome samples. 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.
The ISOGG tree has been described by academics as using the accepted nomenclature for human Y-chromosome DNA haplogroups and subclades in that it follows the Y Chromosome Consortium nomenclature as described in Karafet et al. 2008, [28] [29] [30] The ISOGG tree is widely cited in peer reviewed academic literature.
R-L2 is a human Y-chromosome DNA haplogroup, characteristic of a part of the inhabitants of Italy and Western Europe in general. R-L2 is thought to have originated around the Alps or southern Rhine, additionally, due to R-L2 having split off of R1b-U152 relatively early and it being a major branch, R-L2 carriers were largely contemporary with R-U152 carriers leading to R-L2 also having ...
R-L21 or R1b1a2a1a2c, also known as R-M529 or R-S145, is a Human Y-chromosome DNA haplogroup.It is often linked to the Insular Celts. [1] One subclade, R-DF13 comprises over 99% of bearers.
Haplogroup I (M170) is a Y-chromosome DNA haplogroup. It is a subgroup of haplogroup IJ , which itself is a derivative of the haplogroup IJK . Subclades I1 and I2 can be found in most present-day European populations, with peaks in some Northern European and Southeastern European countries.
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 .
