Question

What is the type of inheritance pattern for the disorder illustrated in the following diagram: 4.2.6?

a) Autosomal dominant
b) Autosomal recessive
c) X-linked dominant
d) X-linked recessive

Answer 1

The type of inheritance pattern for the disorder illustrated in the diagram 4.2.6 is autosomal recessive, making option (b) the correct answer.

Step-by-step explanation:

In the context of genetic disorders, the term "autosomal recessive" refers to a pattern where two copies of an abnormal gene (allele) are necessary for the manifestation of the disorder. Inheritance occurs when both parents are carriers of the abnormal gene, but they do not exhibit symptoms.

The diagram 4.2.6 suggests that the disorder follows this recessive pattern, as the affected individual likely inherited one abnormal allele from each parent. Autosomal recessive disorders often skip generations and may appear when both parents, though unaffected themselves, are carriers of the abnormal gene. This characteristic inheritance pattern distinguishes it from autosomal dominant and X-linked patterns.

Option B is the answer.
