Scientists discover why fathers usually don’t pass on their mitochondria’s genome
The study states that mitochondrial DNA - the genetic code that serves as the powerplant of every cell is passed on by the mother of the child. | Health
Scientists have long recognized the fact that mitochondrial DNA (mtDNA) comes exclusively from egg cells in humans. In a new study, researchers have discovered that while mature sperm do carry a small number of mitochondria, they lack intact mtDNA.
New research provides insight about the bedrock scientific principle that mitochondrial DNA — the distinct genetic code embedded in the organelle that serves as the powerplant of every cell in the body — is exclusively passed down by the mother.
