<unk>  traits behave according to the model of monogenic or<unk>  gene inheritance in which one gene corresponds to one trait. Discrete traits (as opposed to continuously varying traits such as height) with<unk><unk>  inheritance patterns are relatively rare in nature, and many of the clearest examples in<unk>  cause disorders. Discrete traits found in<unk>  are common examples for teaching<unk> .
