>The Nicaragua zoo said Nieve was the first-ever white tiger born in the country, to a pair of yellow-and-black-coloured Bengals. The cub's mother, rescued after she was abandoned by a circus, had inherited the rare gene from her grandfather, who was white. All the white tigers in captivity are descended from the same sire. The entire bloodline is inbred. It would be exciting if there were another instance of a white tiger, so they could stop being inbred.
