If bred to a correctly marked dog carrying for mismarks, then one would have a one in 4 chance for a puppy to be a mismark. IF the correctly marked dog wasn't carrying for mismark, then there would be no chances of mismarks.
Markings might not show up in the next generation, but those markings will show up on down the line at some point in time and pretty identical to their great grandparent's.

Debbie,
I'm sorry but I completely disagree with this explanation. I doubt that there is a gene for white ear, but, what is probably going on is random expression of a pigment gene. If you can send me a refereed paper on this I will admit my mistake, but, color (pigment) should and will turn on randomly. A line would have to be pretty tightly bred, almost clonal in makeup to have identical expression of color placement. There are just too many factors involved to say that a mismark whether white eye patch, off color ear, etc to be genetic.
Also, don't take my disagreement as not respecting your opinion. I very much value your input and our discussions! This is how I am becoming a more informed and responsible pet owner.
Oh, and who came up with the term Whitelies and Bluies? I read the Pem standard today and thought I had misread the words.
