South African White Lions

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 they have never been common in the wild. Regarded as divine by locals, white lions first came to public attention in the 1970s in Chris McBride’s book The White Lions of Timbavati. The greatest population of white lions is in zoos where they are deliberately bred for color. The population of the white lion is unknown but the most recent count was in 2004 and 30 were alive.White lions are not albino lions. Instead, thewhite color is caused by a recessive gene known as chinchilla or color inhibitor. Coloration gives white lions a distinct disadvantage in nature because they are highly visible. This gives them away to theirprey and makes them 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
