雄性孔雀鱼以平均每5分钟7-13次的速度向雌性孔雀求爱，但雌性孔雀对这些显示的反应很少，如果有的话。雌性往往在新雄性进入实验室种群后的30分钟内对其表现做出反应。如果第一只雄蜂的颜色与第一只雄蜂的颜色不同，雌蜂对第二只雄蜂的反应与第一只雄蜂的颜色不同，但如果颜色相似，雌蜂的反应很少。繁殖实验表明，稀有雄性交配的成功率明显高于普通雄性。雌性对稀有或新奇雄性的偏爱可能是自然界中观察到的雄性第二性着色极端多态的进化和维持的部分原因。
Male guppies, P. reticulata, court females at the rate of 7-13 displays/5 min on the average, yet female responses to these displays are seldom if ever observed. Females tended to respond to the displays of a new male within 30 min of his introduction to a laboratory population. Females responded to a 2nd male added to a 1-male, 2-female population if its coloration was different from the first, but responses were rare if coloration was similar. Breeding experiments suggested that rare males were significantly more successful in mating than were common ones. Female preference for rare or novel males may be partially responsible for the evolution and maintenance of the extreme polymorphism in male secondary sexual coloration observed in nature.
