Just tossing this out there...you said "it's" parents...do you know if this BP is male or female? I personally would not invest in a normal male if you plan to breed. I would get a normal female and then spend the money and get a nice stud male. Just my 2 cents, the only snake I own that is not in my breeding program is my original normal male I got at a pet store, I love him, but no point in breeding him.
As was stated, Lessers are codoms...not recessives. Definately do some homework on genetics to better understand the different percentages of breeding what to what. Your snake (in the photo) is a normal. No other genes in there. So don't let them charge you more because they are telling you one of the parents was a Lesser. I have heard of some people doing that which is not right. This is an awesome forum with a ton of great information. Best of luck to you with your breeding project!
