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.

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 ...
The last study, conducted in 2009 by Hammer and Behar et al., [73] says 20 of the 21 Cohen haplogroups have no single common young haplogroup; five haplogroups comprise 79.5% of all haplogroups of Cohen. Among these first 5 haplogroups, J-P58 (or J1E) accounts for 46.1% of Cohen, and the second major haplogroup, J-M410 or J2a accounts for 14.4% ...
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 ]
Haplogroup U is a human mitochondrial DNA haplogroup (mtDNA). The clade arose from haplogroup R, likely during the early Upper Paleolithic.Its various subclades (labelled U1–U9, diverging over the course of the Upper Paleolithic) are found widely distributed across Northern and Eastern Europe, Central, Western and South Asia, as well as North Africa, the Horn of Africa, and the Canary Islands.
James Mangold misses the era when movies weren’t embarrassed to make audiences feel something. The director of the Bob Dylan musical biopic “A Complete Unknown” and comic book adaptation ...
Climate change will wipe out about $1.47 trillion in U.S. home values over the next three decades and hasten economic gaps in U.S. communities, a report released on Monday finds. Already high ...
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.
