Abstract Animal and plant species exhibit an astonishing diversity of sexual systems, including environmental genetic determinants sex, with the latter material in mitochondrial genome. In several hermaphroditic plants for example, sex is determined by interaction between cytoplasmic male sterility (CMS) genes nuclear restorer genes. Specifically, CMS involves aberrant that prevent pollen development specific restore it, leading to a mixture female (male‐sterile) individuals population (gynodioecy). Such mitochondrial‐nuclear determination system thought be rare outside plants. Here, we present one possible case animals. We hypothesize only exception strict maternal mtDNA inheritance animals, doubly uniparental (DUI) bivalves, might have originated as sex‐determination system. document explore similarities exist DUI CMS, propose various ways test our hypothesis.
