Anerythristic boas are not hypos they are anerys. These are two different genetic mutations. Hypos are a lack of black and anerys are a lack of red. They look nothing alike. It has not been proven that orange tails and samons are the same. Also there is another line. I think it is Sharron, boa woman, that produced them. They are a different hypo with out a doubt. Here is a page of boa morphs.
