In mitochondrial genetics, Haplogroup B is a human mitochondrial DNA (mtDNA) haplogroup. Mitochondrial genetics is the study of the Genetics of the DNA contained in Mitochondria. In Human genetics, a human mitochondrial DNA haplogroup is a Haplogroup defined by differences in human mitochondrial DNA.
Haplogroup B is believed to have arisen in Asia some 50,000 years before present. Its ancestral haplogroup was Haplogroup R. In Human genetics, Haplogroup R is a Human mitochondrial DNA (mtDNA haplogroup.
Haplogroup B is found more often in East Asia[1]. Its subgroup B2 is one of five haplogroups found in the indigenous peoples of the Americas, the others being A, C, D, and X. In Human genetics, Haplogroup A is a human mitochondrial DNA (mtDNA haplogroup. In Human mitochondrial genetics, Haplogroup C is a Human mitochondrial DNA (mtDNA haplogroup. In Human genetics, Haplogroup D is a Human mitochondrial DNA (mtDNA haplogroup. In Human mitochondrial genetics, Haplogroup X is a Human mitochondrial DNA (mtDNA haplogroup which can be used to define genetic Populations.
Since the migration to the Americas by the ancestors of Native Americans is generally believed to have been from Siberia, it is especially surprising that Haplogroup B is the only haplogroup found in Native Americans which is not found in modern North Siberian populations. There are several popular models of migration to the New World proposed by the anthropological community Siberia (Сиби́рь Sibir) is the name given to the vast region constituting almost all of Northern Asia and for the most part currently serving Siberia (Сиби́рь Sibir) is the name given to the vast region constituting almost all of Northern Asia and for the most part currently serving However, Haplogroup B has been found among Southern Siberians, such as Tuvans, Altays, and Buryats. Tuvans or Tuvinians ( Tuvan: Тывалар Tyvalar) are a group of Mongols or Turkic people. The Altay or Altai are an ethnic group of Turkic people living in the Siberian Altai Republic and Altai Krai and surrounding areas The Buryats or Buriyads, numbering approximately 436000 are the largest ethnic minority group in Siberia and are mainly concentrated in their homeland the This haplogroup is also found in Mongolians, Tibetans, Koreans, and among populations of Japan, China, Taiwan, Indonesia, Madagascar, The Philippines, Polynesia and Micronesia. Mongolia (mɒŋˈɡoʊliə, literally Mongol country/nation,) is a Landlocked Country in East The Tibetan people are indigenous to Tibet and surrounding areas stretching from Central Asia in the North and West to Myanmar and China Proper The Korean people are an East Asian Ethnic group. Most Koreans speak the Korean language. For a topic outline on this subject see List of basic Japan topics.

In his popular book The Seven Daughters of Eve, Bryan Sykes named the originator of this mtDNA haplogroup Ina. The Seven Daughters of Eve (2001 ISBN 0-393-02018-5 is a book by Bryan Sykes that presents the theory of Human mitochondrial genetics to a general audience Bryan Sykes is Professor of Human Genetics at the University of Oxford and a Fellow of Wolfson College.
