… It has been proposed that B chromosomes might accumulate DNA from various sources (Beukeboom
1994a) existing as amalgamations of transposable DNA. This has been suggested …

Speciation has been a major focus of evolutionary biology research in recent years, with many
important advances. However, some of the traditional organising principles of the subject …

The haplodiploid sex determining mechanism in Hymenoptera (males are haploid, females
are diploid) has played an important role in the evolution of this insect order. In Hymenoptera …

We report here genome sequences and comparative analyses of three closely related
parasitoid wasps: Nasonia vitripennis, N. giraulti, and N. longicornis. Parasitoids are important …

Arising from MA Nowak, CE Tarnita & EO Wilson Nature466, 1057–1062 (2010)10.1038/nature09205

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 …

Background Adult house flies, Musca domestica L., are mechanical vectors of more than 100
devastating diseases that have severe consequences for human and animal health. House …

▪ Abstract Genetic mechanisms of sex determination are unexpectedly diverse and change
rapidly during evolution. We review the role of genetic conflict as the driving force behind this …

Sperm‐dependent (or pseudogamous) forms of parthenogenetic reproduction occur in a wide
variety of animals. Inheritance is typically clonal and matroclinous (of female descent), but …

Insects exhibit a variety of sex determining mechanisms including male or female heterogamety
and haplodiploidy. The primary signal that starts sex determination is processed by a …
