Many genes that mediate sexual reproduction, such as those involved in gamete
recognition, diverge rapidly, often as a result of adaptive evolution. This widespread …

Sexual selection has a reputation as a major cause of speciation, one of the most potent
forces driving reproductive isolation. This reputation arises from observations that species …

A large portion of the annotated genes in Drosophila melanogaster show sex-biased
expression, indicating that sex and reproduction-related genes (SRR genes) represent an …

Developing new regulation of existing genes is likely a key mechanism by which organismal
complexity arises in evolution. To examine plasticity of gene regulation over evolutionary …

A growing number of genes involved in sex and reproduction have been demonstrated to be
rapidly evolving. Here, we show that genes expressed solely in spermatozoa represent a …

Many genes in higher eukaryotes show sexually dimorphic expression, and these genes
tend to be among the most divergent between species. In most cases, however, it is not …

▪ Abstract The evolution of proteins involved in reproduction is only now beginning to be
studied. A reoccurring observation is the rapid evolution of the molecules mediating …

Studies of morphology, interspecific hybridization, protein/DNA sequences, and levels of
gene expression have suggested that sex-related characters (particularly those involved in …

Drosophila melanogaster males transfer seminal fluid proteins along with sperm during
mating. Among these proteins, ACPs (Ac cessory gland p roteins) from the male's accessory …

Gene duplication and domain accretion are thought to be the major mechanisms for the
emergence of novel genes during evolution. Such events are thought to have occurred at …
