Behavioral difference depend on the dog, the age the dog is neutered and other factors. Lots of studies on the topic but mostly you avoid the heightened mating response to other dogs in heat and chance breeding. Behaviorally, effects are generally not that much otherwise.
Coat question….
-
When we got Kona he had a little bit of darker fur around his white markings on his back…well now it is a line the whole way down his back about 2 or three inches wide. Its not that noticeable....it kinda looks like he's just ruffled up haha I just wondered if their coats change at all...he's a little over 5 months old.

Puppies usually "blow" their baby coat after teething and the color fo the coat will change at time…. So yes their coats to change, but not a lot... just like some pedigrees have black masking aroung the face (muzzle and eyes) that will fade with age. Also on Basenjis, the white never changes size... so a big white spot will be much smaller when full grown. Looking at the picture of your Kona, I would say that the white between his eyes was almost the entire area between the eyes when born
