First cousins once removed have a coefficient of relationship of r=6.25% (1/16). Half-first cousins also have r=6.25%. Second cousins have r=3.1% (1/32), third cousins have r=0.8%, fourth cousins have r=0.2%.
People with a coefficient of relationship below 0.1% (half-fourth cousins and more remote) usually do not have a closer genetic relationship than with the average person from their population, and cannot be readily identified by genetic testing.[1]
