Chromosome studies in the male and female bushbuck (Tragelaphus scriptus) are discribed. The male has a diploid chromosome number of one fewer than the female, and the Y-to-autosome fusion. The configuration of a quadrivalent observed in meiotic preparations from the male confirmed the presence of a fusion between a Y chromosome and an autosome. All other members of the tragelaphine tribe so far studied chromosomally show the presence of a Y-to-autosome fusion. It is postulated that the fusion observed in all present-day species of the tribe studied to date arose as a single event in a common ancestor.
本文描述了雄性和雌性薮羚（Tragelaphus scriptus）的染色体研究。雄性的二倍体染色体数目比雌性少一个，存在Y染色体与常染色体的融合。在雄性减数分裂制片中观察到的四价体构型证实了Y染色体与常染色体之间存在融合。迄今为止，在染色体方面进行过研究的薮羚族的所有其他成员都显示存在Y染色体与常染色体的融合。据推测，在迄今所研究的该族所有现存物种中观察到的这种融合是在一个共同祖先中作为单一事件出现的。
