Chromosomal evolution of the Canidae
The Giemsa-banding patterns of chromosomes from the arctic fox ( Alopex lagopus), the red fox ( Vulpes vulpes), the kit fox ( Vulpes macrotis), and the raccoon dog ( Nyctereutes procyonoides) are compared. Despite their traditional placement in different genera, the arctic fox and the kit fox have a...
