The white lion is occasionally found in wildlife reserves in South. It has been perpetuated by selective breeding in zoos around the world. White lions are not a separate subspecies and theyhave never been common in the wild. Regarded as divine by locals, white lions first came to public attention in the 1970s in Chris McBrides bookThe White Lions of Timbavati. The greatest population of white lions is in zoos where they are deliberately bred forcolor. The population of the white lion is unknown but the most recent count was in 2004and 30 were alive. White lionsare not albino lions. Instead, the white color is caused by arecessive gene known as chinchilla or color inhibitor. Coloration gives white lions a distinct disadvantage in nature because they are highly visible. This gives themaway to their prey and makesthem an attractive target for hunters. The chinchilla mutation, a recessive gene, gives white lions their unusual colors. A similar gene also produces white tigers. White lions in canned hunt camps have been found to have hind-limb paralysis and serious heart defects, indicating a severe level of inbreeding involved in mass-production although they are rare in the wild.
