Chromosomal evolution of the Canidae
The Giemsa banding patterns of seven canid species, including the grey wolf ( Canis lupus), the maned wolf ( Chrysocyon brachyurus), the bush dog ( Speothos venaticus), the crab-eating fox ( Cerdocyon thous), the grey fox ( Urocyon cinereoargenteus), the bat-eared fox ( Otocyon megalotis), and the f...
