Questions: Both hypercholesterolemia and Huntington disease display an autosomal (not X- or Y-linked) inheritance pattern.

The answer is: dominant

Explanation:

• Hypercholesterolemia and Huntington disease both exhibit an autosomal dominant inheritance pattern. This means that only one copy of the altered gene, inherited from either parent, is sufficient to cause the disorder.
• In autosomal dominant conditions, the trait or disorder can be passed on to offspring even if only one parent carries the gene mutation.
• This pattern is different from autosomal recessive inheritance, where two copies of the mutated gene (one from each parent) are necessary for the trait or disorder to manifest.

In summary, the correct term to fill in the blank is "dominant," as both conditions are inherited in an autosomal dominant manner.
