Genetics R Fun. As a side note... for similar genetic reasons the "designer" dog breeds (Labradoodle, Yorkipoo, Schnoodle, etc...) often cannot be reliably bred within their "breed" as you will lose many of the effects of the crossbreeding due to the genetic dice rolling snake eyes. Granted the Labradoodle is much further along in it's breeding regimen due to good handling at the second and third generational levels... but that's a whole different discussion.
