D.n. nasuta, D.n. albomicans, Cytorace I and Cytorace II [Chromosoma, 93 (1986) 243] are closely related strains of the nasuta subgroup. Through male choice and female choice experiments, the pattern of sexual isolation if any, among them was analysed. Differential mating preference of males and females of these races suggests that they are passing through the process of anagenesis. Therefore, this, as an evolutionary experiment under laboratory conditions, offers a rare opportunity to witness different pattern and levels of divergence among four cytogentically parsimonious races of Drosophila.
纳苏塔果蝇指名亚种、纳苏塔果蝇白变种、细胞族I和细胞族II [《染色体》，93 (1986) 243] 是纳苏塔亚组的密切相关品系。通过雄蝇选择和雌蝇选择实验，分析了它们之间（若存在的话）的性隔离模式。这些品系的雄蝇和雌蝇的不同交配偏好表明它们正处于前进演化过程中。因此，作为实验室条件下的一项进化实验，这提供了一个难得的机会来见证果蝇四个细胞遗传学简约品系间不同的分化模式和程度。
