Abstract

The chromosomes of the red (Indian) muntjac (2n = 6 female, 7 male), the Chinese (Reeves) muntjac (2n = 46), and their F1 hybrids were studied with various banding techniques. G-banding showed that the two complements still have a high degree of homology despite the vast difference in diploid numbers between the two species. Cd-banding suggested that the X chromosome and chromosome 1 of the red muntjac are dicentric. Evidence indicates that both centric and repeated tandem translocations among the chromosomes of the Chinese muntjac evolved to form those of the red muntjac.

摘要

利用各种显带技术对赤麂（印度麂，2n = 6，雌性；2n = 7，雄性）、中国麂（黑麂，2n = 46）及其杂种F1的染色体进行了研究。G显带显示，尽管这两个物种的二倍体数目差异很大，但它们的两套染色体仍具有高度的同源性。Cd显带表明，赤麂的X染色体和第1号染色体是双着丝粒的。有证据表明，中国麂染色体间的着丝粒易位和串联重复易位共同进化形成了赤麂的染色体。
