In December 2005, a study of the golden strain identified the gene responsible for its unusual pigmentation as SLC24A5, a solute carrier that appeared to be required for melanin production, and confirmed its function with a Morpholino knockdown.
En 2005, nun estudo da cepa golden identificouse o xene responsable desta pigmentación inusual, que era o SLC24A5, un transportador de solutos que parecía ser necesario para a produción de melanina, e confirmouse a súa función cun knockdown con Morpholino.
