The study investigates the selective breeding of two ornamental fish varieties, Red Melon (RM) and Red Cover (RC) discus, focusing on their unique skin pigment patterns resulting from genetic changes over generations.
Skin samples from juveniles and adults were analyzed, revealing differences in types of pigment cells (xanthophores, erythrophores, and melanophores) and associated genes, particularly indicating a unique process driving the development of these pigments in RM juveniles.
This research is the first of its kind to detail how genetic expression influences the growth of skin pigments in red discus, providing insights into their distinct color patterns as ornamental species.
