Abstract We have used human chromosome-specific painting probes for in situhybridization on Indian muntjac ( Muntiacus muntjak vaginalis,2 n= 6, 7) metaphase chromosomes to identify the homologous chromosome regions of the entire human chromosome set. Chromosome rearrangements that have been involved in the karyotype evolution of these two species belonging to different mammalian orders were reconstructed based on hybridization patterns. Although, compared to human chromosomes, the karyotype of the Indian muntjac seems to be highly rearranged, we could identify a limited number of highly conserved homologous chromosome regions for each of the human chromosome-specific probes. We identified 48 homologous autosomal chromosome segments, which is in the range of the numbers found in other artiodactyls and carnivores recently analyzed by chromosome painting. The results demonstrate that the reshuffling of the muntjac karyotype is mostly due to fusions of huge blocks of entire chromosomes. This is in accordance with previous chromosome painting analyses between various Muntjac species and contrasts the findings for some other mammals (e.g., gibbons, mice) that show exceptional chromosome reshuffling due to multiple reciprocal translocation events.
