I have a black bee female which only shows signs when she eats. She gets so excited her head bobs up and down, but she's a deadly shot. I also have a spider het clown that shows zero signs. Both eat live and frozen thawed just fine, the black bee, if she touches the hair on my arm or I touch a rat pup to her nose, will wipe her nose off, which is kinda hysterical to watch, but she goes back to normal. Neither do the upside down slither or anything. Both came from the same breeder who tries not to carry on the line if there is any wobble in the parents. Can it be bread out, I certainly don't know.

I do plan on breeding my snakes, but I will not breed these two females (even thought the possibilities are awesome with my banana and pastel). I see no reason to amplify the trait or carry on the gene. Some i've seen as babies are atrocious. The two I have, didn't have any immediate sign.

To each their own. It's all good. Do what is good in your conscience.
