I can understand why you would say that because of how people talk snake lingo, however...
Being a dominant morph means the heterozygous (het) form and homozygous (super) form look exactly a like. You can see this with the pinstripe and congo.
There however is know homozygous spider, therefore every spider is heterozygous (het) spider. In the case of mojave, mojave would be the heterzygous (het) form and super mojave would be the homozygous form. so all mojaves are also hets.
How ever the snake lingo drops alot of these words to shorten things up, we normally only say hets with talking about recessives, but actually every morph has a heterozygous and homozygous form (spider is still up for debate on the homozygous thing)
