in my honest opinion, breeding a male boa to his half sister would:
not be enough to be considered 'inbreeding' to the point of deformities and other malaties.

be just enough to stick with the lineage (color/pattern/look) while still introducing new blood and keeping it fresh.

not be enough to prove out a certain gene or trait in an animal through extensive filial generations.


my only concern would be if these are albinos with KNOWN issues...
for instance, if one of their parents were a deformed albino (ie. missing eye), and these half related offspring ALBINOS were bred back to eachother, I think that would still give problems. I would stay away from that.

in just about any other case out there, you should be fine.
