It was from a hidden gene pair. I have often wondered what the homozygous form if it existed of the regular Woma would look like. From what I have recently heard, Brian at BHB has tried it a few times with nothing exceptional popping out.
Also, there was a picture a couple years ago from Kevin that should a Lesser Pearl that appeared to have some pretty good size to it (somewhere around 500 grams judging by the other snakes in the pic). I don't know if that animal lived any longer than a year, it may have, but it may mean that another gene added to the Pearl may strengthen it enough to make it survive. Maybe we will learn more this year about the project. Every year that goes by is another year worth of experience working with many of these genes that are actually in there infancy even if they have been around for 10 years.
