Most animals are sexually dimorphic, but different taxa have different sex-specific traits.
Despite major differences in the genetic control of sexual development among animal …

▪ Abstract For 600 million years, the two best-understood metazoan species, the nematode
Caenorhabditis elegans and the fruit fly Drosophila melanogaster, have developed …

Sexually dimorphic abdominal pigmentation and segment morphology evolved recently in
the melanogaster species group of the fruitfly Drosophila. Here we show that these traits are …

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 …

The Drosophila melanogaster sex hierarchy controls sexual differentiation of somatic cells
via the activities of the terminal genes in the hierarchy, doublesex (dsx) and fruitless (fru) …

Primary sex-determination" switches" evolve rapidly, but Doublesex (DSX)-related
transcription factors (DMRTs) act downstream of these switches to control sexual …

The doublesex (dsx) gene is known as the final gene of the sex-determining cascade in
Drosophila melanogaster. We have isolated a homologue of dsx in the silkworm, Bombyx …

Almost every animal lineage is characterized by unique sex-specific traits, implying that such
traits are gained and lost frequently in evolution. However, the genetic mechanisms …

There has recently been a revolution in our understanding of how the Drosophila sex-
determination hierarchy generates somatic sexual dimorphism. Most significantly, the sex …

Abstract doublesex (dsx) is unusual among the known sex-determination genes of
Drosophila melanogaster in that functional homologs are found in distantly related species …
