It's probably important to note, that mutations must occur on different gene pairs (alleles). So if you breed a homozygous mutated ball, to another mutated ball, and the alleles for the mutations are the same, it will likely result in bending space-time... or the slightly more likely fact, you won't get any babies (that are alive anyway).
