high (scary voice) so beware
If a man who is heterozygous for the Hurlington disease alleles has children with a woman who does not have the alleles, there is a 50% chance that each of their children will inherit the disease allele. Since Hurlington disease is autosomal dominant, inheriting just one copy of the disease allele will result in the individual being affected by the disorder.
The offspring will inherit one dominant allele from the homozygous dominant male and have a 50% chance of inheriting the dominant allele from the heterozygous female. Therefore, the ratio of offspring with the dominant allele to those without will be 1:1.
If carried on a dominant allele, you either inherit it- and have the disease- or you don't- and do not have the disease, nor the gene that causes it. If you don't have the gene, you can not pass it to your offspring.
if an indivigual has a dominent allele for a disease he/she is an affected individual.
A person who has one dominant and one recessive copy of a disease gene is typically considered to be affected by the condition if the disease is caused by the dominant allele. In this case, the dominant allele's effects will manifest, overshadowing the recessive allele. The individual may not express traits associated with the recessive allele, as the dominant trait takes precedence.
Huntington's disease is caused by a dominant allele

Dominant genetic diseases are inherited in an autosomal dominant pattern, meaning that only one copy of the mutated gene from an affected parent is sufficient to express the disease. This means that each child of an affected individual has a 50% chance of inheriting the mutated gene and, consequently, the disease. The presence of the dominant allele can mask the effects of a normal allele, leading to the condition even if the other allele is unaffected. Examples of such diseases include Huntington's disease and Marfan syndrome.

Huntington's Disease.
Huntington's Disease
The allele that is fully expressed when carried by only one of a pair of homologous chromosomes is called a dominant allele. Dominant alleles mask the expression of recessive alleles when present in the genotype.
Yes, Huntington's disease is autosomal dominant with high penetrance. Every individual who inherits the allele gets the disease.
