Mitochondrial DNA polymorphisms and sperm motility in Mytilus edulis (Bivalvia: Mytilidae).

Abstract excerpt

The system of mitochondrial DNA (mtDNA) inheritance in Mytilus and other bivalves, termed doubly uniparental inheritance (DUI), is novel among animals. Males pass on their male transmitted (M-type) mtDNA from fathers to their sons whereas females pass on their female transmitted (F-type) mtDNA from mothers to both sons and daughters. Thus, Mytilus males contain two distinct types of mtDNA. Interestingly, sperm...
