TL;DR: Comparison genome-wide analyses of 20 bower-building species of Lake Malawi cichlid fishes found that these phenotypes have evolved multiple times with thousands of genetic variants strongly associated with this behavior, suggesting a polygenic architecture.

TL;DR: It is demonstrated that pits and castles are evolutionarily labile traits and have been derived numerous times in multiple Malawi genera, and traits at multiple biological levels act to regulate the evolution of a courtship behavior within natural populations.

TL;DR: It is discovered that two paralogous androgen receptor genes control social status in the African cichlid fish Astatotilapia burtoni in a highly modular manner, and that ARβ, but not ARα, is required for testes growth and bright coloration, while ARα and ARβ are required for the performance of reproductive behavior and aggressive displays.

TL;DR: Investigations of whole-genome sequencing and phenotypic data for 87 behavioral traits from the Drosophila Genetics Reference Panel indicate that courtship and feeding behaviors have significantly greater genetic contributions and that, in general, behavioral traits overlap little in individual base pairs but increasingly interact at the levels of genes and traits.

TL;DR: The results indicate androgen signaling is necessary for social ascent and hormonal signaling and social experience may shape the full suite of DOM‐typical behavioral patterns.
