Chromosome banding patterns of Lepus saxatilis, 2n = 48, and Pronolagus rupestris, 2n = 42, are presented. Comparison of G-banded karyotypes allows the identification of similar elements in both species. The karyotype of P. rupestris differs from that of L. saxatilis by the presence of three fusions in the former. Comparative studies with the fusion products of Oryctolagus cuniculus indicate that fusion and not fission is the major factor in chromosomal evolution of these leporids. The chromosomal conservatism of the hares is compared to the karyotypic variability of the rabbits and possible causes are discussed.
本文展示了岩兔(2n = 48)和岩兔属(2n = 42)的染色体带型。对G带核型的比较有助于识别两个物种中的相似元素。岩兔属的核型与岩兔的核型不同,前者存在三次融合。与穴兔融合产物的比较研究表明,融合而非分裂是这些兔科动物染色体进化的主要因素。将野兔的染色体保守性与家兔的核型变异性进行了比较,并讨论了可能的原因。
