Why do the two sexes have different lifespans and rates of aging? Two hypotheses based
on asymmetric inheritance of sex chromosomes (“unguarded X”) or mitochondrial genomes …

Sexual conflict occurs when selection acts in opposing directions on males and females.
Case studies in both vertebrates and invertebrates indicate that sexual conflict maintains …

Mitochondria are maternally transmitted; hence, their genome can only make a direct and
adaptive response to selection through females, whereas males represent an evolutionary …

The maternal transmission of mitochondrial genomes invokes a sex-specific selective sieve,
whereby mutations in mitochondrial DNA can only respond to selection acting directly on …

The extent to which mitochondrial DNA (mtDNA) variation is involved in adaptive
evolutionary change is currently being reevaluated. In particular, emerging evidence …

The exchange of genetic material between cellular organelles through intracellular gene
transfer (IGT) or between species by horizontal gene transfer (HGT) has played an important …

Due to their strict maternal inheritance in most animals and plants, mitochondrial genomes
are predicted to accumulate mutations that are beneficial or neutral in females but harmful in …

Background Disorders of the mitochondrial respiratory chain are heterogeneous in their
symptoms and underlying genetics. Simple links between candidate mutations and …

Eukaryotic cells typically contain numerous mitochondria, each with multiple copies of their
own genome, the mtDNA. Uniparental transmission of mitochondria, usually via the mother …

The presence of doubly uniparental inheritance (DUI) in bivalves represents a unique mode
of mitochondrial transmission, whereby paternal (male-transmitted M-type) and maternal …
