It's not a matter of you CAN'T, it's a matter of unknown outcomes if you do. There are dozens of species of animal that have similar problems. To point out a few; Leucistic Carpet Pythons (JagxJag), Blue Merle genes in canines, high white genes in Bull Dogs (can cause deafness), high white genes in horse (very similar to rats), etc. Like I said, it's not a matter of impossibility, there are just certain genes to be weary of.![]()
