Well then if you have to ask if breeding a male to his mother's sister (his aunt) is the same DNA, then I hope you aren't even considering doing the breeding. It is quite obvious that you have little knowledge on genetics. The other "Breeder" who lacks knowledge about correct terminology nor doesn't know the difference between the terms was the one who first suggested you had an oops litter. I agreed by your question that it sounded like you had an oops litter. By your lack of knowledge as well, I just hope you don't do a purposeful breeding of this type
