果蝇包括三种地理类型，分布在美国、下加利福尼亚半岛和墨西哥大陆。选择半岛型和大陆型是为了增加彼此的性别隔离，而保持对照的是最大限度的近亲繁殖。对选择的反应是高度不对称的，在选定的半岛雄性和大陆雌性之间隔离非常高，但在选定的大陆雄性和半岛雌性之间不存在隔离。这种高度的孤立主要是由于男性半岛的一些变化。
Drosophila mojavensis comprises three geographic forms occurring in the United States, the Baja California peninsula, and mainland Mexico. Peninsular and mainland forms were selected for increased sexual isolation from each other, while controls were maintained with maximum outbreeding. Response to selection was highly asymmetrical in that isolation was very high between selected peninsular males and mainland females, but nonexistent between selected mainland males and peninsular females. The heightened isolation is primarily due to some change in the peninsular males.
