The ability to reproduce is the key trait that distinguishes living organisms from inorganic
matter, and the strategies used to achieve successful reproduction are almost as diverse as …

Synopsis “Sex” is often used to describe a suite of phenotypic and genotypic traits of an
organism related to reproduction. However, these traits—gamete type, chromosomal …

The predominance of sex in eukaryotes is still enigmatic. Sex, a composed process of
meiosis and mixis cycles, confers high costs but the selective advantages remain unclear. In …

Severe fever with thrombocytopenia syndrome virus (SFTSV) is spreading rapidly in Asia.
This virus is transmitted by the Asian longhorned tick (Haemaphysalis longicornis), which …

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

Parasitoid wasps are among the most speciose animals, yet have relatively few available
genomic resources. We report a draft genome assembly of the wasp Diachasma alloeum …

Why and how sexual reproduction is maintained in natural populations, the so-called “queen
of problems,” is a key unanswered question in evolutionary biology. Recent efforts to solve …

Over the last decade, genetic studies on social insects have revealed a remarkable diversity
of unusual reproductive strategies, such as male clonality, female clonality, and social …

Parthenogenesis is an asexual reproduction mode characterized by the development of a
female oocyte without fertilization. From an evolutionary perspective, parthenogenesis …

Asexual reproduction has evolved repeatedly from sexual ancestors across a wide range of
taxa. Whereas the costs and benefits associated with asexuality have received considerable …
