For all of a dog’s DNA, there are two copies: one from mom, one from dad. Sometimes, these copies are different in code (A’s, T’s, C’s and G’s). So, this number is what percentage of the dog’s DNA code differs between copies. If the parents are very similar in their DNA, as with purebreds, then this percentage will be low.
