<em>The reasons why we mightt not see a response to directional selection on such a trait are:</em>
- <em>More offspring are produced than can survive.</em>
- <em> Organisms are capable of producing more offspring than their environments can support. </em>
- <em>Offspring vary in their heritable traits. </em>
