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 …

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 …

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

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

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 …

Abstract The Japanese rhinoceros beetle Trypoxylus dichotomus is a giant beetle with
distinctive exaggerated horns present on the head and prothoracic regions of the male. T …

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 …

Eusocial insects such as termites, ants, bees, and wasps exhibit a reproductive division of
labor. The developmental regulation of reproductive organ (ovaries and testes) is crucial for …

Horns or hornlike structures in beetles have become an increasingly popular study system
for exploring the evolution and development of secondary sexual trait diversity and sexual …

Insects are the only known animals in which sexual differentiation is controlled by sex-
specific splicing. The doublesex transcription factor produces distinct male and female …
