so i have an 08' pastel, got him at the hamburg reptile show, i was looking at his belly today and i noticed he kinda looks like a yellow belly compared to the pics online, not a strong yellow, but its clear with some pattern on his sides that is consistent with YB pastels, what would be the tell tale sign that he could be a YB pastel ? also what are the chances ? is that a recessive trait ? his parents were both pastels... thanks ahead of time for any help/insight
