Yellow Belly This morph is another co-dominant morph with the Ivory as its super form. Animals tend to exhibit a lot of yellow within the pattern most noticeable along the lower part of the sides and bordering the dark parts of the pattern. The character that distinguishes the yellow belly is on the belly surprisingly enough and yes some do indeed have yellow/cream bellies but most have an immaculate white belly. Along the sides of the belly bordering both sides are a series of grey and yellow scales running the length of the snake and this is the signature of the morph. Yellow bellies are a very useful morph not only producing the Ivory but when combined with other morphs have a tendency to brighten colour and distort patterns a must for any collection
