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]
In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non-recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share similar numbers of short tandem repeats (STRs) and single-nucleotide polymorphisms (SNPs). [ 2 ]
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 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
Y-Chromosome Haplogroups all form "family trees" or "phylogenies", with both branches or sub-clades diverging from a common haplogroup ancestor, and also with all haplogroups themselves linked into one family tree which traces back ultimately to the most recent shared male line ancestor of all men alive today, called in popular science Y ...
Phylogenetic tree of human mitochondrial DNA (mtDNA) haplogroups Mitochondrial Eve L0: L1–6 ... additional terms may apply. By using this site, ...
Phylogenetic tree of haplogroups I (left) and W (right). Kya in the left scale bar stands for thousand years ago. This phylogenetic tree of haplogroup W subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation [2] and subsequent published research.
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. It is inherited by all modern non-African populations, as well as by some populations ...
