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 …

The question of how new species evolve has been examined at every level, from
macroevolutionary patterns of diversification to molecular population genetic analyses of …

The processes that underlie mate choice have long fascinated biologists. With the advent of
increasingly refined genetic tools, we are now beginning to understand the genetic basis of …

Insects display a staggering diversity of mating and social behaviours. Studying these
systems provides insights into a wide range of evolutionary and behavioural questions, such …

Sex differences in dioecious animals are pervasive and result from gene expression
differences. Elevated sexual selection has been predicted to increase the number and …

Coyne and Orr found that mating discrimination (premating isolation) evolves much faster
between sympatric than allopatric Drosophila species pairs. Their meta-analyses …

Although many theoretical models of sympatric speciation propose that genes responsible
for assortative mating amongst incipient species should be associated with genomic regions …

Dosage compensation, the process whereby expression of sex-linked genes remains similar
between sexes (despite heterogamety) and balanced with autosomal expression, was long …

Polyandry is widespread in nature, and has important evolutionary consequences for the
evolution of sexual dimorphism and sexual conflict. Although many of the phenotypic …

Exposing sires to various environmental manipulations has demonstrated that paternal
effects can be non-trivial also in species where male investment in offspring is almost …
