Description
Maria-Eleni Parakatselaki and four colleagues present a 2026 study showing that fathers' mitochondrial DNA leaking into offspring is genetically controlled in fruit flies. Mitochondrial DNA is normally inherited only from the mother, and leakage has been treated as random error.
Crossing several Drosophila simulans lines with a sister species, the team measured mixed mitochondrial types in hybrids. Leakage levels ran consistently within families, repeated across experiments, and ran higher in males than females. Estimated heritability was high, and wild-derived lines varied more than inbred stocks. The authors argue leakage is a governed trait with possible long-term effects on mitochondrial genome stability.
