The first type of DNA testing used for Genealogical research was the Mitochondria DNA. Mitochondrial (mtDNA) is found in organelles found in the cell nucleus. Mitochondrial was discovered as having it's own DNA make up in 1963, though public testing didn't begin until the 1990s.

Mitochondrial DNA (mtDNA) has specific functions like all other DNA. These functions tell the cells what to do and where to go.

Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA. Because mtDNA is not highly conserved and has a rapid mutation rate, it is useful for studying the evolutionary relationships.

In mussels, it is known to have Mitochondria inherited from the male, though it is very uncommon in all living things. Mitochondria is passed from the mother. She passes Mitochondria to both her male and female offspring, though the male will not pass it to the next generation.

There are now tests that can analyze your Mitochondrial (mtDNA) to find out your maternal family history. You can test for ethnicity, migration, and match up with living relatives. The test also finds mutations in your mtDNA and can help you understand your biology. Maternal Lineage Test at Family Tree DNA

Mutations of mtDNA can lead to a number of illnesses. Mitochondrial Disease. These disease can also be understood better with a Maternal Lineage Test.
