50/50 Cal. King

what do you mean that its 50/50

That means that it was bred for a higher white coloration in the pattern, as opposed to their normal wild-type pattern that had a much smaller percentage of white.

Today, some have been progressively refined to have a MUCH higher percentage of white than years ago.

But many years ago, this was "cream of the crop" as far as a clean, high white Cal.King was concerned.

50 percent white/50 percent black
