Inheritance of shoulder spotting in the jewel tetra, Hyphessobrycon callistus.
Subspecies of Hyphessobrycon callistus exhibit a relatively uniform body color without markings or with a prominent shoulder spot dorsal to the pectoral fins. Segregation patterns observed in the progenies from seven different matings indicate a single-factor inheritance of shoulder spotting, with complete dominance of the spotted phenotype.
