Haplogroup

Uncommon card · No. 111928

A haplotype is a group of alleles in an organism that are inherited together from a single parent, 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 identified by a particular single-nucleotide polymorphism (SNP) mutation. More specifically, a haplotype is a set of closely linked alleles that tend to be inherited together. As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from a haplotype. Haplogroups represent a single paternal or maternal line of descent. For example, membership in Haplogroup R-M269 by any individual relies on a relatively small proportion of that individual's genetic material of the genetic material possessed by that individual. Each haplogroup originates from, and remains part of, a preceding single haplogroup (or paragroup). As such, any related group of haplogroups may be precisely modelled as a nested hierarchy...
