Development of a cytogenetic map for the Chinese raccoon dog (Nyctereutes procyonoides procyonoides) and the arctic fox (Alopex lagopus) genomes, using canine-derived microsatellite probes.

New chromosomal assignments of canine-derived cosmid clones containing microsatellites to the Chinese raccoon dog and arctic fox genomes are presented in the study. The localizations are in agreement with data obtained from comparative chromosome painting experiments between the dog and arctic fox genomes. However, paracentric inversions have been detected by comparing the loci order in canid karyotypes. The number of physically mapped loci increased to thirty-five both in the Chinese raccoon dog and in the arctic fox. Furthermore, the present status of the cytogenetic map of the Chinese raccoon dog and arctic fox is presented in this study. Copyright 2003 S. Karger AG, Basel
