Homozygous Tobiano and W20!

This horse is homozygous for Tobiano and heterozygous for W20. Because Tobiano and W20 are both KIT gene mutations (essentially), the only way this is possible is for W20 to be linked to Tobiano. This means that W20 and Tobiano are on the same allele and one copy of Tobiano will always be inherited with W20. Photo courtesy of Bexlee Miniatures
