Not all KKPs can close their mouth. Parrots without the "parrot notch" where the head meets the body are classified as KKP. There are high grade and low grade KKPs, one with a mouth that can't close but no notch is a low grade KKP.

It really depends on who you're talking to, there aren't really any set rules. Some people say "high grade BP" and some say "low grade KKP" to describe the same fish. I'm of the persuasion that a fish like this:
is considered a KKP because of its shape and notchlessness, though it has a mouth that doesn't close. It's all pretty hazy though because KKP's and BP's are all just different grades of fish that are produced in the exact same batches. In a batch of parrots, you'll get fish with notches and non closing mouths (BP's), fish with notches and mouths that close (still a BP), and fish without notches with closing or non-closing mouths, which I and others consider to be KKP. You also get rose queens from those batches.
Also when breeding a KKP or BP with a FH or Texas, the mouth shape of the parrot doesn't really matter. I've seen parrots with closing mouths produce fry with the open mouth, and I've seen lots of open mouth parrots produce tons of fry with closing mouths.
