The predominance of sexual reproduction indicates that it must confer profound benefits,
considering its significant costs relative to asexuality. However, definitively determining …

Explaining the selective forces that underlie different reproductive modes forms a major part
of evolution research. Many organisms are facultative sexuals, with the ability to reproduce …

Triploids are rare in nature because of difficulties in meiotic and gametogenic processes,
especially in vertebrates. The Carassius complex of cyprinid teleosts contains sexual …

Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis
and the fusion of two gametes of different sexes or mating types. Sex-determination …

Plant-parasitic nematodes are major agricultural pests worldwide and novel approaches to
control them are sorely needed. We report the draft genome sequence of the root-knot …

Horizontal gene transfer in metazoans has been documented in only a few species and is
usually associated with endosymbiosis or parasitism. By contrast, in bdelloid rotifers we …

Bdelloid rotifers are notorious as a speciose ancient clade comprising only asexual
lineages. Thanks to their ability to repair highly fragmented DNA, most bdelloid species also …

DNA modifications are used to regulate gene expression and defend against invading
genetic elements. In eukaryotes, modifications predominantly involve C5-methylcytosine …

Rotifers of class Bdelloidea are common invertebrate animals with highly unusual
characteristics, including apparently obligate asexuality, the ability to resume reproduction …

Bdelloid rotifers are microinvertebrates with unique characteristics: they have survived tens
of millions of years without sexual reproduction; they withstand extreme desiccation by …
