mtDNA

Mitochondrial DNA (mtDNA) is a type of genetic material found in mitochondria, the energy-producing structures within our cells. Unlike most DNA, which is inherited from both parents, mtDNA is passed down exclusively from mothers to their children. This unique inheritance pattern makes mtDNA useful for studying ancestry and evolution, as it can trace maternal lineages over generations. Additionally, mtDNA can help in understanding certain genetic diseases that arise from mitochondrial dysfunction. Essentially, mtDNA plays a crucial role in energy production and is key to exploring our genetic heritage.
