本文分析了冈比亚拟南毛猴和阿拉伯拟南毛猴实验室种群和自然种群有丝分裂染色体的Hoechst 33258带型。观察到性染色体异染色质明显的种内多态性。在每个物种中，异色变异都属于一种特有的物种模式。当实验室种群对给定的异色变异倾向于单态时，自然种群表现出高度的种群内多态性。本文讨论了性染色体异染色质在控制按蚊繁殖和交配行为中的可能作用。
The Hoechst 33258 banding pattern of the mitotic chromosomes of several laboratory and natural populations of the sibling species A. gambiae and A. arabiensis was analyzed. A clear intraspecific polymorphism of sex chromosome heterochromatin was observed. In each species heterochromatic variations fall within a characteristic species-specific pattern. While laboratory populations tend to be monomorphic for a given heterochromatic variant, natural populations exhibit a high degree of intrapopulation polymorphism. The possible role of sex chromosome heterochromatin in controlling fertility and mating behavior of Anopheles spp. mosquitoes is discussed.
