Black and White Explained
  Black and White: (ABCDEgmrsi/spt) This color is produced the same as a Black dog with the exception of carrying a different gene that produces varying amounts of white. This color is dominant in nature and will re-produce itself regardless of what color it is bred to. If your dog is Black and White the (S) gene would be replaced with one of these White producing gene patterns, (si, or sp) in any combination. For more info see White Chart.
