Not all rusties are het. leucy, but many leucys are in reality rusty. Rusty is co-dominant, which means that those leucistic black rats bred to a normal black rat would produce half normal, half rusty babies. So, I guess yes, MANY rusties are het leucy, but not all. The only ones I've ever seen in person, I know for a fact aren't, and have never been bred with anything except direct descendants of wild-caught rusty black rats.
Seems like a lot of people bred their rusty black rats with leucistic rats, which may be how the rumors started that rustys aren't pure black rats(as many leucs are crosses between black & Texas rats).
>>Sure is worthy of a dinking project.Good luck with it.Nice snake.By the way,are all rustys het.leucy?How does that work.Would leucy.to normal produce rustys?
