+**Mitochondrial DNA** (mtDNA) is a small, circular chromosome nestled within [Mitochondria](/wiki/mitochondria), distinct from the cell's nuclear genome. Inherited almost exclusively from mother to child, it offers a direct path to tracing ancient [Maternal Lineage](/wiki/maternal_lineage) through time. This unique inheritance makes mtDNA a key in evolutionary studies and human population genetics.
