They may or may not be normal looking.
It is possible that the hyper in Cal Kings is to some extent compatible with the hyper in MBK.
The hyper in MBK is clearly different and does not seem to be simple Mendel genetics, but it is possible that it does or can involve a gene compat. with Cal King hyper, and there may be more than on Cal King hyper gene because some hyper Cal Kings have a pattern mutation going as well (Davis/Mendota) while some hyper Cal Kings do not (LA county).
I can't wait for the Hubbs book.
Someone should donate or loan a sexually mature Davis Hyper to Shannon to pair with his clovis black belly male and see if maybe the black belly and the hyper black belly are related or allelic.

Note to OP - the following are Cal King x MBK that I produced this year - all have sock heads, and while you can see the Cal King influence, they also look to have splendida like influence.


In 2 to 3 years (I'm guessing 2, these guys are feeding well and growing FAST) - I will hopefully pair my male blizzard cal king with my female holdback from the cross - which should produce amels het for hyper and double hets that are 3/4 cal king, 1/4 mbk. (these crosses are het amel). However, I won't list them as het hyper because if hypermelanism expresses itself in a future generation, there really is no way to know for sure if it is hyper from Cal King gene or hyper from the MBK influence.
In my cross - all 11 babies produced look somewhat similar, but another person who did the cross this year got two different phenotypes - some look similar to mine, and some are not nearly as dark and don't have sock heads. So MBK x Cal King does not necessarily mean sock head.
I have a suspicion that there may be different "flavors" of MBK and that can't be visually distinguished - some with more hypermenalism causing genes than others, but even those with less hypermelanism genes still appear fully black as adults.
