John,
I would not get your hopes up on the striped trait proving to be genetic with those greeri. It was most likely incubation related since the striped specimen has some fused ventral scales. Furthermore, another striped specimen was never again produced from that pair of adults. I know, because I bought them from my friend here in CT who produced the striped greeri. I had the striped parents for a few years and all their offspring came out normal. Eric got them from me and has had them for a couple years now. I don't believe he's produced a striped greeri either.
None the less, it's still a very unusual and neat snake. DV
