<u>Linkage</u> is the term applied when two genes fail to assort independently.
<h3><u>RESULT</u>?</h3>
☆The result is that <em>the parental traits will be maintained</em>.
☆ Also, the linked genes sit close together on a chromosome, making them likely to be inherited together (left).
<h3><u>IMPORTANCE</u></h3>
When the chromosomal location for a disease phenotype has been established, then the genetic <em>linkage </em><em>s</em><em>c</em><em>r</em><em>u</em><em>t</em><em>i</em><em>n</em><em>y</em><em> </em><em>helps determine whether the disease phenotype is only caused by mutation</em> in a single gene or mutations in other genes, giving rise to an identical or similar phenotype.
