This genetic defect occurs when two merle coloured dogs are bred. It doesn't matter if they are blue merle or red merle the key here is that the puppies inherit two dominant merle genes (MM). This double whammy of the merle gene results in a homozygus merle or double merle puppy often referred to as a lethal white.
I didn't know cattle dogs could be lethal whites because there really isn't a "merle" cattle dog, they are all spotted.
