In the study of molecular evolution, a haplogroup (from the Greek: ἁπλοῦς, haploûs, “onefold, single, simple”) is a group of similar haplotypes that share a common ancestor.
DNA Haplgoups are an indication of “Deep Ancestry”. That is an attempt to identify the very early ancestral group from which one is descended 12,000 to 70,000 years ago. This can give one an indication of where his/her ancestors originated.
In human genetics, the haplogroups most commonly studied are Y-chromosome (Y-DNA) haplogroups and mitochondrial DNA (mtDNA) haplogroups, both of which can be used to define genetic populations. Y-DNA is passed solely along the patrilineal line, from father to son, while mtDNA is passed down the matrilineal line, from mother to daughter. Neither recombines, and thus Y-DNA and mtDNA change only by chance mutation at each generation with no intermixture between parents’ genetic material.
