Huntington's disease is an inherited autosomal dominant disorder that can affect both men and women. Imagine a couple has had seven children, and later in life, the husband develops Huntington's disease. He is tested and it is discovered he is heterozygous for the disease allele, Hh. The wife is also genetically tested for the Huntington's disease allele, and her test results show she is unaffected, hh.

Explanation:
Huntington's disease: is an autosomal dominant disorder.
given
male = Hh
female = hh
H =dominant allele
h = recessive allele
All child inherit one allele from each parent, one from father and one from mother.
So parents are
1).
Hh and hh
F1 progeny are (Hh, Hh, hh and hh)
50% show Huntington's disease ( Hh, Hh)
so there are 50% chances that first child have Huntington's disease
2).
Any two of the seven children will have Huntington's disease
