Abstract

New Robertsonian (Rb) populations of the house mouse (Mus musculus domesticus) carrying different combinations of centric fusions are reported in France, Switzerland, and Germany. In Alsace (France), the diploid number varied from 2n = 38 to 34; four fusions were present, with Rb(4.12) homozygous in all populations whereas Rb(5.10), Rb(5.7), or Rb(10.14) were found to be segregating. In Switzerland, only all-acrocentric mice (2n = 40) were present in Bern while Rb(5.7) and Rb(9.16) occurred in Basel. In the Konstanz locality from southern Germany, all the mice were homozygous for nine Rb fusions: Rb(1.18), Rb(2.5), Rb(3.6), Rb(4.12), Rb(7.15), Rb(8.17), Rb(9.14), Rb(10.11), and Rb(13.16). The phylogenetic relationship of these new Rb populations with those already known is discussed.

摘要

在法国、瑞士和德国报道了小家鼠（Mus musculus domesticus）携带不同着丝粒融合组合的新罗伯逊易位（Rb）种群。在法国阿尔萨斯地区，二倍体数目从2n = 38变化到34；存在四种融合，所有种群中Rb(4.12)均为纯合子，而Rb(5.10)、Rb(5.7)或Rb(10.14)呈分离状态。在瑞士，伯尔尼只有全端着丝粒小鼠（2n = 40），而巴塞尔出现了Rb(5.7)和Rb(9.16)。在德国南部的康斯坦茨地区，所有小鼠对于九种Rb融合均为纯合子：Rb(1.18)、Rb(2.5)、Rb(3.6)、Rb(4.12)、Rb(7.15)、Rb(8.17)、Rb(9.14)、Rb(10.11)和Rb(13.16)。讨论了这些新Rb种群与已知种群的系统发育关系。
