However, this is not always the case if we take an example of the ancient man where the Homo sapiens and the Homo erectus interbred to produce viable offspring with a higher brain capacity (Douglas).

The word capable here means that the organisms are free and willing to mate naturally to reproduce. It is true that the anatomy of many organisms qualifies their ability or inability to mate. However, if there is no reproductive isolation, organisms of different species are capable of fertile interbreeding.

For instance, taking the German Shepherds as an example, they are cross breed of dogs and wolves and they are known for their high intelligence, strength, and obedience training. An example of an infertile offspring is the mule- a result of the interbreeding between a horse and a donkey.

The relationship between phenotype, genotype, and natural selection is essential to the knowledge of heredity and development organism.
