Question

Imagine that one of your parents had Huntington's disease. What is the probability that you, too, will someday manifest the disease? There is no cure for Huntington's. Would you want to be tested for the Huntington's allele? Why or why not?

Answer 1

Answer:

There is a 50% chance of getting Huntingdon's disease.

Explanation:

Assume the affected parent is Hh, where H is the Huntingdon's disease allele and h is the unaffected allele. One parent is unaffected, or hh. You have a 50% chance of getting the H allele from the affected parent.

If I had the choice to get tested, for Huntingdon's disease, I would do it.  I would want to know so that I wouldn't  live my life worrying about it everyday.
