Butter x lesser produces BEL?

[Russ Lawson]

Now though this is true that they make bels, but if you do cross Butter to Lesser and was looking sell the babies; 1) How could you tell the difference? 2) Wouldn't it look bad on the breeder by mixing the Butter and Lesser lines?

You couldn't tell the babies apart because lesser and butter are the same allele. I have a hard time thinking people would see outbreeding two lines of the same mutation as a bad thing. You could just call any heterozygous offspring butter/lesser. I've seen it done before.
