I haven't the experience with boa's to comment on the possible genetics at play here so I'll just say it's nice crossed with nicer. In the end, if this is a pet and not a snake you're going to breed from, then it's really a moot point. Looks like a lovely boa, sounds like it's got a great temperment so enjoy. I may be primarly focused on ball pythons, but our home would seem empty without a boa in it.
