本文报道了白额狐猴L.fulvusalbifrons，L. rubriventer及其与L. fulvus fulvus与L.黄色的L. fulvus具有相同的核型。L. rubriventer与L. fulvus的五个罗伯逊易位，也增加了异染色质的X染色体的着丝粒区域。在本研究中的核型与其他狐猴相比，使我们能够提出一个一般的计划，代表狐猴属的染色体进化。在这属罗伯逊易位代表29到目前为止已确定的33个染色体重排。我们不能肯定杂种的不育完全是由于罗伯逊易位的积累。
The karyotype of Lemur fulvus albifrons, L. rubriventer and its hybrids with L. fulvus fulvus were compared with that of L. fulvus fulvus. The two subspecies of L. fulvus have the same karyotype. L. rubriventer differs from L. fulvus by five Robertsonian translocations and also by increased heterochromatin in the juxtacentromeric region of the X chromosome. The karyotypes in the present study compared with those of other lemurs allowed us to propose a general scheme representing the chromosomal evolution of the genus Lemur. In this genus Robertsonian translocations represent 29 of the 33 chromosomal rearrangements which have so far been identified. We cannot affirm that sterility of the hybrids is exclusively due to the accumulation of Robertsonian translocations.
