The paper describes the cellular expression and genetics of the Purple Body trait in guppies and its interactions with other coloration genes under different light conditions.

The paper identifies the Purple Body gene in Poecilia reticulata, showing it modifies coloration and is inherited as an autosomal incompletely dominant trait.

This study identifies chromatophore types and their interactions in the ocular media of guppies, revealing a complex UV-filtering mechanism that provides a private signaling system.

The paper describes the phenotypic expression of the Purple Body gene in domestic guppy strains, highlighting its role in modifying coloration and the creation of new phenotypes when combined with other mutant genes.
