You are getting into complicated territory regarding the genetic testing of cannabis cultivars. It's a certain the this will happen but in regards to the cultivars that have come out of Amsterdam, In most cases, as in Paradise's, they originate from all the same Skunk (Cheese) and Haze families so that may not be possible in this case.
Other companies importing more genetically unique cultivars will be able to do this and I'm sure they will, even going as far as to insert suicide genes to hamper any crossing another breeder may try and do.
