1) 25%
2) 50%
3) 75%
4) 100%

Answer 1

If your mother is normal but your father is heterozygous for Huntington's disease, your chances of escaping the disease entirely is 50%.

Step-by-step explanation:

The chances of escaping Huntington's disease entirely, if your mother is normal but your father is heterozygous for the disease, is 50%. Huntington's disease is a dominant genetic disorder, which means that if one parent has the disease, each child has a 50% chance of inheriting it. In this case, since your mother does not carry the disease, you have a 50% chance of escaping the disease.
