Quizplus · Accepted Answer

Huntington disease is an autosomal dominant disorder. Autosomal dominant inherited conditions affect
female and male family members equally and follow a vertical pattern of inheritance in families. A person who has an autosomal dominant inherited condition carries a gene mutation for that condition on one chromosome pair. Each of that persons offspring has a $50 \%$ chance of inheriting the gene mutation for the condition and a $50 \%$ chance of inheriting the normal version of the gene.
