If both parents have the same marking with a known mutation (the best example I can think of being leopard and addition leopard, since both are very different) could their offspring produce the mutated marking AND the standard marking as the two possible markings? If it can occur, could it happen if only one parent has the marking?
Just something that popped into my head and that I was curious about. Don't feel rushed in answering, and I know when it comes to breeding mutations and the like, you want to all be in agreement and on the same page.
Thanks for answering my, prolly a bit weird, question. Sorry if the answer is somewhere about marking mutations. x^x
