Quizplus · Accepted Answer

Since Huntington's disease is an autosomal dominant disorder and the woman is heterozygous, she has one affected allele and one normal allele. With each pregnancy, there is a 50% chance that she will pass on the affected allele to her child. Therefore, the chance that she will pass the affected allele on to her children is 50%.
