Transcriptional regulators related to the invertebrate sexual regulators doublesex and mab-3
occur throughout metazoans and control sex in most animal groups. Seven of these DMRT …

More than 3 percent of the protein sequences inferred from the Caenorhabditis elegans
genome contain sequence motifs characteristic of zinc-binding structural domains, and of …

Most metazoans occur as two sexes. Surprisingly, molecular analyses have hitherto
indicated that sex-determining mechanisms differ completely between phyla. Here we …

Sex-determining mechanisms are highly variable between phyla. Only one example has
been found in which structurally and functionally related genes control sex determination in …

Sexually dimorphic traits play key roles in animal evolution and behavior. Little is known,
however, about the mechanisms governing their development and evolution. One recently …

Deletion of the distal short arm of chromosome 9 (9p) has been reported in a number of
cases to be associated with gonadal dysgenesis and XY sex reversal, suggesting that this …

Genetic control–the deliberate introduction of genetic traits to control a pest or vector
population–offers a powerful tool to augment conventional mosquito control tools that have …

A wide range of organisms use sex pheromones to communicate with each other and to
identify appropriate mating partners. While the evolution of chemical communication has …

Sexual dimorphisms in trait expression are widespread among animals and are especially
pronounced in ornaments and weapons of sexual selection, which can attain exaggerated …

The Drosophila somatic sex-determination regulatory pathway has been well studied, but
little is known about the target genes that it ultimately controls. In a differential screen for sex …
