African cichlids display a remarkable assortment of jaw morphologies, pigmentation patterns,
and mating behaviors. In addition to this previously documented diversity, recent studies …

Background Tilapias are the second most farmed fishes in the world and a sustainable
source of food. Like many other fish, tilapias are sexually dimorphic and sex is a commercially …

Background African cichlid fishes are well known for their rapid radiations and are a model
system for studying evolutionary processes. Here we compare multiple, high-quality, …

Background MicroRNAs (miRNAs) represent a second regulatory network that has important
effects on gene expression and protein translation during biological process. However, the …

Background Sex-determination genes drive the evolution of adjacent chromosomal regions.
Sexually antagonistic selection favors the accumulation of inversions that reduce …

To determine the visual sensitivities of an organism of interest, quantitative reverse
transcription–polymerase chain reaction (qRT–PCR) is often used to quantify expression of the light‐…

Background Inversions and other structural polymorphisms often reduce the rate of recombination
between sex chromosomes, making it impossible to fine map sex-determination loci …

African cichlids are well known for their adaptive radiations, but it is now apparent that they
also harbor an extraordinary diversity of sex chromosome systems. In this study, we …

Sensory systems are tuned by selection to maximize organismal fitness in particular
environments. This tuning has implications for intraspecies communication, the maintenance of …

Males and females of Artemia franciscana, a crustacean commonly used in the aquarium
trade, are highly dimorphic. Sex is determined by a pair of ZW chromosomes, but the nature …
