I'm sorry when we weaken a gene trait in dogs many of us call it watering or weakening the gene so there is less of a chance of it coming out. I guess it does not apply in snakes, especially since the spider gene is dominant. I guess what i mean is it will have less of a chance to come out. I do like the look of the spider, but don't want to chance having it come up too often. My goal is babies that are healthy, and have the best chance of a long life. I know we have the power to control just certain things, and its up to the universe to control the rest. My concern is i do the best in my power for my babies, because we certainly can't control mother nature.
