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
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.
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 ...
(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.
Haplogroup HV derives from the haplogroup R0, which in turn descends from haplogroup R.HV is also the ancestral clade to the haplogroups H and V.A possible origin of HV haplogroup is in the region of Western Iran, Mesopotamia, and the South Caucasus, where the highest prevalence of HV has been found.
Haplogroup I2a1b-M423 is the most frequent Y-chromosome haplogroup I-M170 in Central and Eastern European populations, reaching its peak in the Western Balkans, most notably in Dalmatia (50–60% [33]) and Bosnia-Herzegovina (up to 71%, [96] avg. 40-50% [33]). Its subclade I-L161 has greater variance in Ireland and Great Britain, but overall ...
London, a city in the United Kingdom, is a large settlement with a human population of 14 million in its metropolitan area.. In geography, statistics and archaeology, a settlement, locality or populated place is a community of people living in a particular place.
