Secondly has nobody wondered why Karin kept a lock of her own hair in her desk? If she needed a genetic sample all she has to do is pluck a hair from her head at any time, and it's not like she left the sample for the others to use since she emphasized to Suigetsu that her desk was private, and not for others to rummage around in. How much do you want to bet that lock of hair is Sasuke's? Karin be pervin. Actually, there are hundreds of lab regulations regarding the storage of genetic material. It has to be kept sterile. It's not as simple as just getting a new extraction for every time you need it. Doctors with their own labs here for example have a variety of their own samples in their lab. Not just material that is harder to extract like urine and blood, but also spit and hair. They use their own extractions for a clear comparison to that of a patient. And they don't throw their own extractions away either. They keep it instead of getting a new one every time. You'd be surprised how long these things can last. Keeping your own samples, especially for Karin, who has one of the most interesting biologies, is absolutely nothing unusual. Not to mention that Sarada and Suigetsu wouldn't mistake a black hair for a red one. Provided this actually was a hair of course.
