User blog comment:Dead Ninja/ Can Ben become a Highbreed/DNAlien/@comment-3549757-20120712080757

Ben does have a sample of the Highbreed, but not the DNAliens. DNAliens are mutations, which is one reason as to why their DNA cannot be scanned. The Omnitrix can only scan pure DNA. DNAliens are also created from those little squid things, of which I have forgotten their names, they are non-sapient and the Omnitrix will only scan sapient beings.
