Yea, the mother is a black tailed animal. It's just interesting how that popped up in a yellow tailed animals lineage, but I guess that kinda stuff happens all the time with species that are bred more frequently. It's kinda like the yellow/white eyed animals. I like the original red eyed individuals personally, but just the difference is cool as well. Interesting as the genetics for the black tailed animal may be (co)-dominant as a regular yellow tailed father to a black tailed mother created a black tailed baby. Unless there's more to it of course?
