The past decade has seen a remarkable revision of perspectives on unisexual reproduction
in vertebrates. One can no longer view it as a rare curiosity far outside the mainstream of …

Theory suggests that occasional or conditional sex involving facultative switching between
sexual and asexual reproduction is the optimal reproductive strategy. Therefore, the true …

Root-knot nematodes (genus Meloidogyne) exhibit a diversity of reproductive modes
ranging from obligatory sexual to fully asexual reproduction. Intriguingly, the most …

Coevolutionary antagonism generates relentless selection that can favour genetic
exchange, including transfer of antibiotic synthesis and resistance genes among bacteria …

Evolution without sex is predicted to impact genomes in numerous ways. Case studies of
individual parthenogenetic animals have reported peculiar genomic features that were …

Sexual reproduction is both extremely costly and widespread relative to asexual
reproduction, meaning that it must also confer profound advantages in order to persist. One …

We summarize current knowledge on the structure of mating type loci in different species of
basidiomycetes, giving special consideration to bipolar and tetrapolar heterothallic species …

Understanding the maintenance of sexual reproduction constitutes a difficult problem for
evolutionary biologists because of the immediate costs that sex seems to incur. Typically …

Sexual reproduction is widely regarded as one of the major unexplained phenomena in
biology. Nonetheless, while a general answer may remain elusive, considerable progress …

Asexual reproduction in animals, though rare, is the main or exclusive mode of reproduction
in some long-lived lineages. The longevity of asexual clades may be correlated with the …
