Genetics+Of+White+Horses+Unraveled

July 23, 2008 The reason why white horses are white is because of a mutation. The mutation also causes an increased risk of tumors. This mutation makes the horses grey faster so by the age of one they are grey. They turn white by the age of six or seven. The horses are born with regular colors like brown, but because of the early graying they end up white. It’s just like the graying in humans but much faster. Theses horses all have the same mutation. "It is a fascinating thought that once upon a time a horse was born that turned grey and subsequently white and the people that observed it were so fascinated by its spectacular appearance that they used the horse for breeding so that the mutation could be transmitted from generation to generation," says Leif Andersson. People across the world admire theses white horses not knowing what makes them like that. Kim Bigos March 14 2010
