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 …

Understanding how genes influence behavior, including sexuality, is one of biology's
greatest challenges. Much of the recent progress in understanding how single genes can …

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 …

The years following the 1985 publication of Comprehensive Insect Physiology, Biochemistry
and Pharmacology have been marked by stunning developments in insect science. A …

Propagation in higher animals requires the efficient and accurate display of innate mating
behaviors. In Drosophila melanogaster, male courtship consists of a stereotypic sequence of …

The Drosophila roX1 gene is X-linked and produces RNAs that are male-specific, somatic,
and preferentially expressed in the central nervous system. These RNAs are retained in the …

The doublesex gene of Drosophila melanogaster is the final member of a well characterized
hierarchy of genes that controls somatic sex determination and differentiation. The male …

The fra-7 gene is the terminal control gene for somatic sex determination in the nematode
Caenorhabditis elegans. Here we identify two fra-7 mRNAs: one is a 1.5 kb transcript that …

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 …

Dmrt1 (doublesex and mab-3 related transcription factor 1) is a conserved transcriptional
regulator of male differentiation required for testicular development in vertebrates. Here, we …
