Well, when you take away just the red we know the polymorphic and polygenic capabilities in garters should be taken into consideration also Joe. I think there are and can be alot of factors at play in individual animals. You certainly could be right. However this is also a young animal in Zdravs link but trust me i have seen a anerythrystic parietalis that was a adult and looked very similar to phenotype of this one. I can't really say i have seen a melanistic parietalis before. Melanistic sirtalis, yes.
