We breed out certain things we do not want in the breed, yet they keep popping back up after hundreds of breedings, the info was never lost it just wasn't dominate until the right dogs were breed and bang there is that old thing we were trying to breed away into a recessive gene that wouldn't rear it's ugly head. We even have data bases with dogs to help us to breed out traits we do not want to have such as the white patches that come up on their chest from time to time, this gene is hundreds of years old and try as we may it is still rearing it's ugly head, even in the highest quality Rottweilers.
It's precisely because the white patch is produced by a recessive gene that it's difficult for you to breed it out. It means that you could be propagating the genes for this trait throughout your population of dogs without realising it. And not all genes are recessive. If they were then we wouldn't have to call it a recessive gene, we'd just call it a gene. If it was a dominant gene then it would be easy to get rid of.
What this should be telling you is just what kind of time scales are involved with the evolutionary process. Religionists always make an unfounded assumption that natural processes work on timescales relative to their lifetime yet they have no basis for making this assumption.
And ironically, having recessive genes helps a species avoid becoming trapped in evolutionary dead-ends because the genes can persist in the population without lowering the fitness of the carrier, yet can prove beneficial if the environment changes later on.
I'd just like to finish by saying that pedigree dog breeders are evil scum who breed populations of unhealthy dogs fated to either suffer from birth or have a short life span. And they do this merely for their own arbitrary aesthetic satisfaction.
Just let dogs be happy, healthy dogs and stop using some kind of canine eugenics to breed fucking short lived freaks destined to suffer.
