Solution

The question seems to be incomplete, but based on the information given, if heterozygotes are unaffected, it suggests an autosomal recessive disorder.

Here's why:

  1. In genetics, a heterozygote is an individual having two different alleles of a particular gene or genes, and so giving rise to varying offspring.

  2. If a heterozygote is unaffected, it means they are a carrier of the disease but do not show symptoms. This is a characteristic of autosomal recessive disorders.

  3. In an autosomal recessive disorder, two copies of an abnormal gene must be present in order for the disease or trait to develop. A person with an autosomal recessive disorder inherits one abnormal gene from each parent.

  4. In contrast, in an autosomal dominant disorder, an affected person usually has one affected parent. A child of an affected parent has a 50% chance of inheriting the disorder. Therefore, if the disorder was autosomal dominant, a heterozygote would be affected.

So, based on the information given, the answer is an autosomal recessive disorder.
