Butter x lesser produces BEL?

[MitsuMike]

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.

Thanks guys. I have just passed up many Butter males because I want to have it paired with my Lesser girl and didn't want to have the bad rep of mixing lines.
