The mitochondrial DNA is critically important for many of the pathways that produce energy within the mitochondria. And if there's a defect in some of those mitochondrial DNA bases, that is to say a mutation, you will have a mitochondrial disease, which will involve the inability to produce sufficient energy in things like the muscle and the brain, and the kidney. …
Lineage Tracing In Humans Enabled By Mitochondrial ...

Figure 1. Mitochondrial mutations are stably propagated in human cells in vitro. ( A) Dynamics of mtDNA heteroplasmy in single cells. Each cell has multiple mitochondria, which in turn contain many copies of mtDNA that may acquire somatic mutations over time. ( B) Proof-of-principle design.
How many generations back does mitochondrial DNA …

How many generations back does mitochondrial DNA (mtDNA) testing trace? Mitochondrial DNA (mtDNA) testing covers both recent and distant generations. Matching on HVR1 means that you have a 50% chance of sharing a common maternal ancestor within the last fifty-two generations. That is about 1,300 years.

Lineage Tracing in Humans Enabled by Mitochondrial Mutations and Single-Cell Genomics Lineage tracing provides key insights into the fate of individual cells in complex organisms.
Tracking inheritance of human mitochondrial DNA
https://phys.org/news/2019-11-tracking-inheritance-human-mitochondrial-dna.html
"Mitochondrial DNA is inherited from the mother, but only a small number of these copies actually get passed on in each egg. That means that at some point, there is a reduction in the number of ...

Tracking inheritance of human mitochondrial DNA. New insight into how genetic information stored in human mitochondria is passed from one generation to the next could have important implications for genetic counseling of women planning pregnancies, according to a study by researchers at Penn State and the University of California, Berkeley.
mtDNA (Maternal Lineage) Tests - Family Tree DNA
https://learn.familytreedna.com/dna-basics/mtdna/
Your mtDNA can trace your mother, her mother, her mother’s mother, and so forth and offers a clear path from you to a known or likely direct maternal ancestor. Note that you and your matches may share ancestors on other parts of your family tree; however, those matches are coincidental.
Trace Your Maternal Ancestry With mtDNA | …
https://www.familytreedna.com/products/mt-dna
CONNECT WITH mtDNA RELATIVES. Join the world’s largest database of mtDNA testers. Your mtDNA matches will share a common ancestor with you on your direct maternal line. That common ancestor can be recent -meaning within a generation or two - or more distant - living up to or around 1,300 years ago. The tools and data gained through a mtDNA test can help you …
