Popis:	A color mutation of green sunfish (Lepomis cyanellus), resulting in whitish, golden-colored fish, was studied to determine the inheritance and ecological significance of this mutation. The offspring of six golden green sunfish were used in this study. The color trait is recessive and is believed to be caused by a genetically induced malfunction during melanoblast differentiation. The golden green sunfish were slower growing than normal-colored green sunfish from Illinois. Both color morphs, normal and golden, preferred to mate with normal-colored green sunfish. The golden green sunfish were more susceptible to predation by largemouth bass (Micropterus salmoides) than were the normal-colored green sunfish (P
