Research advances in mitochondrial doubly uniparental inheri-tance in bivalves
Eukaryotes have undergone numerous instances of independent evolution to ensure the maternal inheri-tance pattern of organelles.However,certain bivalves have evolved a unique mitochondrial inheritance system known as doubly uniparental inheritance,in which maternal and paternal mitochondrial DNA(F-and M-types,re-spectively)are passed on to offspring.Although the doubly uniparental inheritance pattern was first identified in bivalves over 30 years ago,the genetic mechanisms governing it remain largely enigmatic.This article reviews the doubly uniparental inheritance system,summarizing the current state of research and exploring potential future ap-plications.The uniqueness of this system in bivalves presents an invaluable resource for studies on mitochondrial inheritance and evolution,mito-nuclear conflict,and sex determination.
