Default DNA testing: not GSD

I had a friend ask me if its true that there is DNA testing that will tell what breeds a mix breed dog is? To be honest, I told her I knew DNA is used to tell which is which sire of puppies in a litter if there is more than one, but I was not sure there was a test to say what breeds are in a mix breed dog if you do not have one of the parents.
Anybody help me on this one? If there is a company, who is it and is it accurate?
thanks

Yes, there is but there are questions about how accurate the testing is. I've heard the ones that use blood are more accurate than the ones that use a cheek swab.

Here is some info:

I don't think any of them are accurate. There was a member on here a while back who was a scientist and explained in-depth why they are not accurate - including citing examples of people who sent in samples from their purebred dogs and had them come back as mixes. If you use the search, maybe you can find it? At any rate, I'd save my money.

I haven't looked into the amount of genetic variation between breeds but I wouldn't think it would be that great. I wouldn't spend money on one.

I had my mixed breed, Spirit, tested by 2 different companies and they came up with totally different results. Yeah, they aren't worth the money.

Humans and chimps are about ~98% the same DNA... and dogs are the same species I find DNA based breed tests to be suggestive at best, but anything but conclusive
