Haplogroup C (mtDNA)
Encyclopedia
In human mitochondrial genetics
, Haplogroup C is a human mitochondrial DNA (mtDNA) haplogroup.
.
). Haplogroup C is one of five mtDNA haplogroups found in the indigenous peoples of the Americas
, the others being A
, B
, D
, and X
. The subclades C1b, C1c, C1d, and C4c are found in the first people of the Americas. C1a is found only in Asia.
In 2010, Icelandic researchers discovered a C1 lineage in their home country, estimating an introduction date of 1700 or earlier. A Native American origin for this C1e lineage is likely, but the researchers note that a European or Asian one cannot be ruled out.
of haplogroup C subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation and subsequent published research.

Human mitochondrial genetics
Human mitochondrial genetics is the study of the genetics of the DNA contained in human mitochondria. Mitochondria are small structures in cells that generate energy for the cell to use, and are hence referred to as the "powerhouses" of the cell....
, Haplogroup C is a human mitochondrial DNA (mtDNA) haplogroup.
Origin
Haplogroup C is believed to have arisen somewhere between the Caspian Sea and Lake Baikal some 60,000 years before present. It is a descendant of the haplogroup MHaplogroup M (mtDNA)
In human mitochondrial genetics, Haplogroup M is a human mitochondrial DNA haplogroup. An enormous haplogroup spanning all the continents, the macro-haplogroup M, like its sibling N, is a descendant of haplogroup L3....

Distribution
Haplogroup C is found in Northeast Asia (including SiberiaSiberia
Siberia is an extensive region constituting almost all of Northern Asia. Comprising the central and eastern portion of the Russian Federation, it was part of the Soviet Union from its beginning, as its predecessor states, the Tsardom of Russia and the Russian Empire, conquered it during the 16th...
