Encyclopedia of mtDNA Origins
Haplogroup A is a branch on the maternal tree of human kind. It is a child of major haplogroup N. It was likely born in East Asia around 24,000 years ago. (Behar et al., 2012b). Through historic travels, members of this line live across East Asia and the Americas.

- Y-DNA Testing for Genetic Genealogy
Y-chromosome DNA, Y-DNA, testing for genetic genealogy is both the second most common type of DNA testing for genealogy and the second type of DNA test to be used in academics to study population histories.
- mtDNA Testing for Genetic Genealogy
An mtDNA test (mitochondrial DNA test) is used for maternal genealogy. MtDNA is passed from a mother to her children. Thus, it traces a direct maternal line. Both men and women can take mtDNA tests.
The Compendium is the start of a comprehensive guide to genetic genealogy terminology, best practices, and science.

- Genome-wide association study of antisocial personality disorder
The pathophysiology of antisocial personality disorder (ASPD) remains unclear. Although the most consistent biological finding is reduced grey matter volume in the frontal cortex, about 50% of the total liability to developing ASPD has been attributed to genetic factors.
- Ancient DNAs and the Neolithic Chinese super-grandfather Y haplotypes
Previous studies identified 3 Neolithic Han Chinese super-grandfather Y haplotypes, O2a2b1a1a-F5, O2a2b1a2a1-F46, and O2a1b1a1a1a-F11, but their relationships with the archaeological and written records remain unexplored. We here report genome wide DNA data for 12 ancient samples (0.02x-1.28x) from China ranging from 6500 to 2500 years before present (YBP).
This contribution describes the discovery and subsequent investigation of a cist in a rock-cut pit at Achavanich, Highland. Discovered and excavated in 1987, the cist was found to contain the tightly contracted skeletal remains of a young woman, accompanied by a Beaker, three flint artefacts and a cattle scapula.
In this study, we examined the genetic diversity and phylogeographic structure of Kazakhstani goats. The mtDNA sequences of 141 Kazakhstani goats were categorized into haplogroups A, C, and D, of which haplogroup A was predominant (97%), whereas haplogroups C and D were detected at low frequencies (1.4% each).

Archaeogenetic analyses are usually aimed at elucidating the demographic history of small-scale societies, although frequently over large geographic and temporal scales.
