title: Do gender table and persons table have an identifying relationship?
body: <p>I have two tables, one is Persons, and the other is Genders, hence I want to put more than two genders, M, F, Other.</p>
  
  <h2>Persons</h2>
  
  <ul>
  <li>id INT (pk, ai)</li>
  <li>fk(gender_id)</li>
  </ul>
  
  <h2>Genders</h2>
  
  <ul>
  <li>id INT (pk, ai)</li>
  <li>title VARCHAR(255)</li>
  </ul>
  
  <p>What would be the relationship type between Genders and Persons table? Is the relationship between them should be non-identifying or identifying (gender_id has to be primary key too)?</p>
  
  <p>Thanks in advance.
