The organisms can produce viable, fertile, offspring; but they cannot produce viable, fertile, offspring with other groups of organisms. Disadvantage- asexual reproduction, some don"t allow you to watch the reproduction, and you can"t use it for. Based on the ability to reproduce distinct organisms: morphological species concept- the group which includes all the organisms which have the same shape and structure.
