Male‐specific exaggerated horns are an evolutionary novelty and have diverged rapidly via
intrasexual selection. Here, we investigated the function of the conserved sex‐determination …

Many scarab beetles have sexually dimorphic exaggerated horns that are an evolutionary
novelty. Since the shape, number, size, and location of horns are highly diverged within …

Sex-specific trait expression is frequently associated with highly variable, condition-
dependent expression within sexes and rapid divergence among closely related species …

Sexual dimorphisms fuel significant intraspecific variation and evolutionary diversification.
Yet the developmental-genetic mechanisms underlying sex-specific development remain …

The sex determination gene doublesex (dsx) encodes a transcription factor with two
domains, oligomerization domain 1 (OD1) and OD2, and is present throughout insects. Sex …

Discovering the mechanisms that underlie the origin of novel features represents a major
frontier in developmental and evolutionary biology. Here we begin to characterize the role of …

Sex in insects is determined by a cascade of regulators ultimately controlling sex-specific
splicing of a transcription factor, Doublesex (Dsx). We recently identified homolog of dsx in …

Background Genes in the sex determination pathway are important regulators of sexually
dimorphic animal traits, including the elaborate and exaggerated male ornaments and …

Sex determination cascade in insects terminates with the production of sex-specific protein,
Doublesex (Dsx). We identified the dsx homolog (Tcdsx) in Tribolium castaneum. The pre …

Alternative splicing underpins functional diversity in proteins and the complexity and
diversity of eukaryotes. An example is the doublesex gene, the key transcriptional factor in …
