已使用限制性内切酶 Taq I、Alu I 和 Hind III 分析了来自两种相关的黑线姬鼠属物种 A. sylvaticus 和 A. flavicollis 的卫星。限制性图谱在物种之间密切保守，并显示出由两种不同限制性酶检测到的 375 个碱基对重复单元内的两种不同内部周期性的新特征。这对根据当前模型引入观察到的限制位点（例如不等交换）施加了限制。讨论了这种保守序列的含义及其在其他物种中的存在。
Satellites from two related species of the Apodemus genus, A. sylvaticus and A. flavicollis, have been analysed with restriction enzymes Taq I, Alu I and Hind III. The restriction maps are closely conserved between species and show a novel feature of two differing internal periodicities within a 375 base pair repeating unit detected by two different restriction enzymes. This places constraints on the introduction of the observed restriction sites according to current models such as unequal crossing-over. The implications of such a conserved sequence and its presence in other species are discussed.
