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 …

Most heritable information in eukaryotic cells is encoded in the nuclear genome, with
inheritance patterns following classic Mendelian segregation. Genomes residing in the …

Molluscs comprise the second largest phylum of animals (after arthropods), occurring in
virtually all habitats. Some are commercially important, a few are pests and some carry …

Background Molluscs are the most diverse marine phylum and this high diversity has
resulted in considerable taxonomic problems. Because the number of species in Canadian …

Many bivalvian mollusks have a sperm-transmitted mitochondrial genome (M), along with
the standard egg-transmitted one (F). The phenomenon, known as doubly uniparental …

Mitochondrial (mt) function depends critically on optimal interactions between components
encoded by mt and nuclear DNAs. mitochondrial DNA (mtDNA) inheritance (SMI) is thought …

Mitochondrial DNA (mtDNA) is predominantly maternally inherited in eukaryotes. Diverse
molecular mechanisms underlying the phenomenon of strict maternal inheritance (SMI) of …

Background Doubly uniparental inheritance (DUI) is an atypical system of animal mtDNA
inheritance found only in some bivalves. Under DUI, maternally (F genome) and paternally …

Recent data from mitochondrial genomics and proteomics research demonstrate the
existence of several atypical mitochondrial protein-coding genes (other than the standard …

In this review, we provide an overview of the current knowledge on the different sexual
systems and sex-determining mechanisms in bivalves, with a focus on the various …
