Purebred is "of only one kind." It's a mix of only ONE species or thing. Hybrid is that two or more things were mixed to create something. For example, a purebred dog is a Poodle, while a hybrid is a Labradoodle.
Geographic isolation: a population is separated by distance or some kind of barrier so the members of the population can't interbreed with the main population. Temporal isolation: Two species that breed at different times of the day, season, or year cannot mix their gametes. Behavioral Isolation. Species-specific signals and elaborate behavioral patterns are used by closely related species to insure contact with the proper mate. Birds, mammals, and insects have pre-mating rituals that attract the proper mate. These signals can be chemical or physical in nature. Other organisms pay little or no attention to these behaviors or scents.
