Gene name - Sex lethal Synonyms - Cytological map position - 6FB3 Function - splice factor Keyword s - sex determination - acts to control sex-specific gene regulation and sexual identity in both the germline and the soma, but acts as a general regulator of X chromosome gene expression and dosage compensation only in the soma. The Wright stuff: Reimagining path analysis reveals novel components of the sex determination hierarchy in Drosophila melanogaster. BMC Syst Biol 9: PubMed ID: Summary : This study used a structural equation modeling approach, leveraging natural genetic variation from two studies on Drosophila female head tissues to expand understanding of the sex hierarchy gene regulatory network GRN.

Sex-lethal - Wikipedia

Sex-lethal Sxl is the master switch gene for somatic sex determination in Drosophila melanogaster. In XX animals, Sxl becomes activated and imposes female development; in X Y animals, Sxl remains inactive and male development ensues. A switch gene for sex determination, called F, has also been identified in the housefly, Musca domestica. An active F dictates female development, while male development ensues when F is inactive.

A major model system for the study of evolutionary divergence between closely related species has been the unisexual lethality resulting from reciprocal crosses of Drosophila melanogaster and D. Sex-lethal Sxl , a critical gene for sex determination, is misregulated in these hybrids. In hybrid males from D. Introduction of a Sxl mutation into this hybrid genotype will allow expression of the MSL complex but there is no sequestration to the X chromosome.
