The study of reproductive isolation and species barriers frequently focuses on mitochondrial
genomes and has produced two alternative and almost diametrically opposed narratives. On …

The partitioning of genetic material between the nucleus and cytoplasmic (mitochondrial and
plastid) genomes within eukaryotic cells necessitates coordinated integration between these …

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

Most aspects of the molecular biology of cells involve tightly coordinated intermolecular
interactions requiring specific recognition at the nucleotide and/or amino acid levels. This …

Metazoans exist only with a continuous and rich supply of chemical energy from oxidative
phosphorylation in mitochondria. The oxidative phosphorylation machinery that mediates …

Mitochondrial genes are widely used in taxonomy and systematics because high mutation
rates lead to rapid sequence divergence and because such changes have long been …

The avian world is packaged into genetic assemblages that we call species. Although
ornithologists can, with a few important exceptions, agree on the boundaries among avian …

In bilaterian animals, the mitochondrial genome is small, haploid, does not typically
recombine, and is subject to accumulation of deleterious alleles via Muller's ratchet. These …

Mitochondrial (mt) and nuclear-encoded proteins are integrated in aerobic respiration,
requiring co-functionality among gene products from fundamentally different genomes …

Nuclear and organellar genomes can evolve at vastly different rates despite occupying the
same cell. In most bilaterian animals, mitochondrial DNA (mtDNA) evolves faster than …
