**Core Concept**
Inbreeding refers to the mating of closely related individuals, which can lead to an increased risk of genetic disorders due to the expression of recessive alleles. This phenomenon is often observed in consanguineous marriages or families with a history of inbreeding.

**Why the Correct Answer is Right**
Inbreeding increases the chances of homozygosity, where an individual inherits two copies of the same allele (one from each parent), leading to the expression of recessive genetic disorders. This is because the gene pool is reduced, and the likelihood of homozygous recessive genotypes increases. For example, in families with a history of cystic fibrosis, the risk of expressing the disease is higher if the parents are related.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not relevant to the concept of inbreeding.
* **Option B:** This option is incorrect because it does not relate to the concept of inbreeding.
* **Option C:** This option might be related to genetic counseling, but it is not directly relevant to the concept of inbreeding.

**Clinical Pearl / High-Yield Fact**
Inbreeding can lead to an increased risk of genetic disorders, and it is essential to consider the family history when evaluating patients with genetic conditions.

**Correct Answer: C.**
