Question

huntington's disease is an incurable, progressive nerve disorder. symptoms of tbe disease generally appear between the ages 30 and 50. the allele for huntington's disease is dominant. is it possible for a child to be born to a parent with Huntington's disease to not develop the disease later in life?

Answer 1

It is possible, but the DNA tells it all.

Answer 2

This would depend on if the other parents has it or not. If they do not, they have a 50/50 chance that the trait will become recessive. That said, it could still be passed on to the child's kids in later generations.
