Unlike the novel where there were only a few cases, every Dinosaur in the first film were created using frog DNA to fill in any gene sequence gaps and therefor capable of breeding. However at no point was this suggested to be a problem with Jurassic World so if anything other that Rexy was used in Jurassic World, they wouls either have been sterilized or the Park Rangers would have to go out any collect any eggs that are laid with any offspring going to the Petting Zoo, though this does create potential issues with over stocking
