Paternally Inherited Mitochondrial DNA

Paternally inherited mitochondrial DNA (mtDNA) refers to mitochondrial genetic material passed from father to offspring. Typically, mitochondria—tiny structures in cells that produce energy—are inherited from the mother, since egg cells contain mitochondria, while sperm cells contribute very little. However, in rare cases, mitochondrial DNA can come from the father, leading to paternal inheritance. Studying these cases helps scientists understand mitochondrial genetics, inheritance patterns, and related diseases. Overall, paternal inheritance of mtDNA is uncommon but offers valuable insights into genetics and cell biology.
