If individuals are able to encounter each other, character divergence may prevent courtship rituals from leading to a mating either because female preferences have changed or male behaviors have changed. These mechanisms of reproductive isolation can be divided into prezygotic mechanisms (those that operate before fertilization) and postzygotic mechanisms (those that operate after fertilization). a. apex consumer b. secondary consumer c. producer d. primary consumer, In a series of experiments the following data table for number of hits vs. trial was constructed.

The Evolution Lab is designed to be implemented in a teaching unit over the course of several class sessions. Postzygotic mechanisms include genetic incompatibilities that prevent proper development of the offspring, or if the offspring live, they may be unable to produce viable gametes themselves as in the example of the mule, the infertile offspring of a female horse and a male donkey.
