Plant and animal karyotypes sometimes contain variable elements, that are referred to as additional or B-chromosomes. It is generally believed that B-chromosomes lack major genes and represent parasitic and selfish elements of a genome. Here we report, for the first time, the localization of a gene to B-chromosomes of mammals: red fox (Vulpes vulpes) and two subspecies of raccoon dog (Nyctereutes procyonoides). Identification of the proto-oncogene C-KIT on B-chromosomes of twoCanidae species that diverged from a common ancestor more than 12.5 million years ago argues against the current view of B-chromosomes. Analyses of fox B-chromosomal …
