The reason you see both colors in some litters...is because the standard colored dog carries two genes. 1 dominant (standard coloring) and 1 recessive. When bred to another dog with the same genetic make up...both must offer the recessive gene for the parti coloring to be expressed (seen).
I have seen people advertising "carriers" for sale ...puppies which are the product of two standard colored parents...and quite honestly there is no way to determine if those puppies are carriers. It is entirely possible the puppy inherited two dominant genes from the parents. |
It's now possible to determine if a traditional colored dog is a piebald carrier, there's a lab in Canada that can DNA test for piebald in the Yorkshire terrier!

If a breeder is so concerned about parti showing up in their litter, they can test their dogs to determine if they carry for off colors (chocolate and gold can also be tested for).
