I've produced Ivories from both an Orangebelly male to a Yellowbelly female and an Orangebelly male to an Orangebelly female. The Ivories that were Orangebelly/Yellowbelly ended up developing Graphite markings at about six months, nine months, and almost 20 months. The Ivories that are Orangebelly/Orangebelly did not develop definitive Graphite markings by the time that I sold the, but at least one of them was showing some possible Graphite markings when I sold her.

I have not bred any of the Ivories, so I don't know if you could really tell the Orangebelly babies from the Yellowbelly babies. I do know that the Orangebellies that I work with look much better than most Yellowbellies, but I don't think you could say for absolute certainty that this is an Orangebelly and this is a Yellowbelly.
