Greg,
I know it is possible in dogs so I don't see why it can't happen in reptiles. We had 2 dogs come in while I was working at the vet clinic that once dna was run showed that each litter had been sired by 2 different males. One litter had a genetic defect so all but 1 puppy died and there were like 11 puppies in that litter so just the 1 puppy had a different sire, needless to say that dumbfounded us all as to how just 1 puppy was sired out of that male.
