Genetic polymorphism varies among species and within genomes, and has important
implications for the evolution and conservation of species. The determinants of this variation …

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

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

Sex strongly impacts genome evolution via recombination and segregation. In the absence
of these processes, haplotypes within lineages of diploid organisms are predicted to …

The dominance of sexual reproduction is still an unresolved enigma in evolutionary biology.
Strong advantages of sex have to exist, because only a few parthenogenetic taxa persist …

Theories on the evolution and maintenance of sex are challenged by the existence of
ancient parthenogenetic lineages such as bdelloid rotifers and darwinulid ostracods. It has …

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 …

In the present study we investigate the genetic diversity within the asexually reproducing
tardigrade Echiniscus testudo. The present study is the first to sample a tardigrade species …

Diversity of most above‐ground organisms increases with decreasing latitude, but the
biogeographical and macroecological diversity patterns of below‐ground animals have …

Genome evolution in asexual organisms is theoretically expected to be shaped by various
factors: first, hybrid origin, and polyploidy confer a genomic constitution of highly …
