Almost all eukaryotes undergo sexual reproduction to generate diversity and select for
fitness in their population pools. Interestingly, the systems by which sex is defined are highly …

Background The predominance of sex in eukaryotes, despite the high costs of meiosis and
mating, remains an evolutionary enigma. Many theories have been proposed, none of them …

The rarity of parthenogenetic species is typically attributed to the reduced genetic variability
that accompanies the absence of sex, yet natural parthenogens can be surprisingly …

Parthenogenesis is rare in nature. With 39 described true parthenogens, scaled reptiles
(Squamata) are the only vertebrates that evolved this reproductive strategy …

Evolutionary transitions from sexual to asexual reproduction should have significant
influences on genetic divergence and polymorphism at the genome level. Plant lineages …

The transition from sexual reproduction to asexuality is often triggered by hybridization. The
gametogenesis of many hybrid asexuals involves premeiotic genome endoreplication …

'Species 'is an iconic term in biology. In addition to the countless concepts and definitions of
the term in biology, in the vernacular it also has important applications, for example, in its …

The adaptive value of sexual reproduction is still debated. A short‐term disadvantage of
asexual reproduction is loss of heterozygosity, which leads to the unmasking of recessive …

Hybridization and genome duplication have played crucial roles in the evolution of many
animal and plant taxa. The subgenomes of parental species undergo considerable changes …

As whole‐genome sequencing has become pervasive, some have suggested that reduced
genomic representation approaches, for example, sequence capture, are becoming …
