| Coat Color and Pattern in English Shepherds Extreme White Extreme white markings are the result of a recessive gene at the white spotting locus. If a dog inherits two copies of the extreme white allele, the dog will be mostly white. If a dog inherits only one copy of the extreme white allele, the amount of white may vary from very little to quite a lot, depending on what the second allele inherited at that locus is. Because extreme white is a recessive pattern, it can result from the crossing of two dogs who have little or no white themselves, but who carry the recessive causing excessive white.
