In human mitochondrial genetics

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....

Origin

A descendant of the macro-haplogroup R

Haplogroup R (mtDNA)

In human mitochondrial genetics, haplogroup R is a very extended mitochondrial DNA haplogroup and is the most common macro-haplogroup in West Eurasia.Haplogroup R is a descendant of macro-haplogroup N...

, Haplogroup JT is the ancestral haplogroup to mitochondrial haplogroups J

Haplogroup J (mtDNA)

In human mitochondrial genetics, Haplogroup J is a human mitochondrial DNA haplogroup.Haplogroup J derives from the haplogroup JT, which also gave rise to Haplogroup T. In his popular book The Seven Daughters of Eve, Bryan Sykes named the originator of this mtDNA haplogroup Jasmine...
