I personally don't know of any sex linkage, but perhaps some of the other breeders can chime in here. I do know that male sperm is greatly affected by temperature. Think of all the studies being done on laptop use and the effect the extra heat has on human male sperm. If kept at either extreme, boa sperm dies too.

As for could all the hypos be slugs and you get a litter of normals, surely that COULD happen. In a perfect world those percentages would be right. If you are proving out a boa and only get 8 babies and not any are the morph you are proving, you probably don't want to come to any conclusions with that few offspring. In a litter of 30 or more babies, you would probably see those percentages more accurately reflected.
