The first animal mitochondrial genomes to be sequenced were of several vertebrates and
model organisms, and the consistency of genomic features found has led to a 'textbook …

Animal and plant species exhibit an astonishing diversity of sexual systems, including
environmental and genetic determinants of sex, with the latter including genetic material in …

There is only one exception to strict maternal inheritance of mitochondrial DNA (mtDNA) in
the animal kingdom: a system named doubly uniparental inheritance (DUI), which is found in …

Heteroplasmy is the presence of more than one type of mitochondrial genome within an
individual, a condition commonly reported as unfavorable and affecting mitonuclear …

Typically, animal mitochondria have very compact genomes, with few short intergenic
regions, and no introns. Hence, it may seem that there is little space for unknown functions in …

Doubly uniparental inheritance (DUI) describes a mode of mtDNA transmission widespread
in gonochoric freshwater mussels (Bivalvia: Palaeoheterodonta: Unionida). In this system …

The class Bivalvia is a highly successful and ancient taxon including∼ 25,000 living
species. During their long evolutionary history bivalves adapted to a wide range of …

Bivalves exhibit an astonishing diversity of sexual systems and sex-determining
mechanisms. They can be gonochoric, hermaphroditic or androgenetic, with both genetic …

Bivalves exhibit an astonishing diversity of sexual systems, with genetic and environmental
determinants of sex, and possibly the only example of mitochondrial genes influencing sex …

Current analysis shows that the last eukaryotic common ancestor (LECA) was capable of full
meiotic sex. The original eukaryotic life cycle can probably be described as clonal …
