Very interesting. I would be happy with it after about 15, with more than one female. I would normally agree that 1 non would definitely be a deal breaker, but you would have to consider sperm retention in that case. If you breed out 100 more all of that morph then you may consider that the one was due to sperm retention.

It is funny my husband and I were discussing how would you know if a BEL had the spider gene? After a lot of debate I finally laughed and said oh duh, you would know when it started doing the Stevie Wonder. But seriously What if you had a super lesser x super mojave. It would still be a BEL but would only throw BELS.
