1. Huntington’s disease (HD), or Huntington’s chorea, is a degenerative nerve disorder with a genetic basis that becomes apparent after about the age 40. The abnormal gene that produces this disease, H, is dominant. The normal, recessive gene is h. One of Heather’s parents has HD but the other doesn’t. Can you predict the highest probability that Heather will develop HD later in her life?

Can someone please help me with this?? I got an answer of a 100% probability that Heather will develop HD but I'm not sure if it's right. Can someone explain this problem and the right answer to me?

Your answer is right if the affected parents genotype is HH. But it could also be Hh. However the non affected parents genotype is hh. So depending on the genotype of the affected adult, she could have a hundred percent chance or a fifty percent chance

Hi, Thank you for the answer. I assumed that the affected parent's genotype is HH since it asks for the highest probability. Do you think my reasoning seems to be correct??
Answered by Varren
HH is the correct answer since it asks for the highest probability
