Sean, not that tough to figure out...In 1997 randy produced double hets but didn't know it at the time. His first anery baby showed up that year but remined a question mark until reproduced in following breedings. littermates were sold to gary keasler simply as albino hets, which subsequently produced possible double hets without keaslers knowledge. Blair could have concievably been the recipent of long odds(possible double hets) and way big good luck(beating odds with 2 snows and 2 anerys in same litter. Amazing!
