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 …

The evolution of reproductive barriers is the first step in the formation of new species and
can help us understand the diversification of life on Earth. These reproductive barriers often …

The main forces directing long-term molecular evolution remain obscure. A sizable fraction
of amino-acid substitutions seem to be fixed by positive selection,,,, but it is unclear to what …

Continuous cell lines that originate from mammalian tissues serve as not only invaluable
tools for life sciences, but also important animal cell substrates for the production of various …

Evolution in allopatric populations can lead to incompatibilities that result in reduced hybrid
fitness and ultimately reproductive isolation upon secondary contact. The D obzhansky–M …

Reduced fitness in interpopulation hybrids can be a first indication of genetic
incompatibilities that may ultimately lead to reproductive isolation and speciation. A growing …

Fundamental biological processes hinge on coordinated interactions between genes
spanning two obligate genomes—mitochondrial and nuclear. These interactions are key to …

Mitochondrial transcription, translation, and respiration require interactions between genes
encoded in two distinct genomes, generating the potential for mutations in nuclear and …

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