Background Information:
You have been married for quite some time and are interested in growing your family. Thalassemia is a disease that runs in one side of the family. You would like to know more about genetic testing and whether or not you should go through with it.

You are curious about how diseases are passed down from one generation to the next and what the likelihood of passing down this disease is, if you’re a carrier. You and your spouse have discussed whether decisions about reproducing should be based on predispositions to a disease. You’ve come to a genetic counsellor to walk you through this emotionally challenging time

How do I demonstrate???
