What is significant about mitochondrial DNA?

The mitochondrial DNA is critically important for many of the pathways that produce energy within the mitochondria. Mitochondrial DNA, unlike nuclear DNA, is inherited from the mother, while nuclear DNA is inherited from both parents.

What is a mitochondrial haplogroup and what information can it provide?

The Maternal Haplogroup Report tells you about your maternal-line ancestors, from your mother through her mother and beyond. Both males and females inherit their mitochondrial DNA and, therefore, their haplogroup assignment from their mothers.

Which is mtDNA haplogroup is native to Africa?

Haplogroup M is a human mitochondrial DNA (mtDNA) haplogroup. An enormous haplogroup spanning all the continents, the macro-haplogroup M, like its sibling the macro-haplogroup N, is a descendant of the haplogroup L3 . All mtDNA haplogroups considered native outside of Africa are descendants of…

How are haplogroups used in the evolutionary tree?

Human mitochondrial DNA haplogroup. In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA. Haplogroups are used to represent the major branch points on the mitochondrial phylogenetic tree. Understanding the evolutionary path of the female lineage has helped population…

How are mitochondrial DNA haplogroups used in genetics?

For populations details, see 1000 Genomes Project#Human genome samples. In human genetics, a human mitochondrial DNA haplogroup is a haplogroup defined by differences in human mitochondrial DNA. Haplogroups are used to represent the major branch points on the mitochondrial phylogenetic tree.

How is mtDNA testing used in genetic genealogy?

There are two ways mtDNA can be tested to help with your genealogy. The first is direct mtDNA testing. This method sequences the entire mitochondrial genome (mtGenome). Results include all variants that exist there. It’s the best method for finding new variants. With direct testing, one can best understand matches. The second is targeted testing.
