As I mentioned before there is no way of knowing how much (or in reality, how little, maybe even none at all) PRB blood there is in any specific BRB line.



Like others have stated, you doing a "cross" and selling the babies as what they are is not the real problem, it's future gens where the true history can (and likely) will be lost.



For example I would expect a variety of babies in that litter. Some displaying more of the PRB traits including scale count and others more along the line of a BRB. Once sold, they could change hands again, even several times to the point nobody knows where it originally came from and humans being anal would look at it and decide it was either PRB or BRB based on visual cues.



Same thing with any subsequent offspring. even 50/50 offspring bred together would not necessarily produce 50/50 offspring. Statistical probability would predict a bell curve distribution with one end picking up more of the original BRB genes and the other end getting more of the PRB genes. Think about it this way, flip a coin ten times and record the results. Often it will be 50/50 heads/tails but sometimes will be 60/40 or 70/30, even 80/20 or 90/10 and not very often but rarely it will be all ten heads or tails.
