**Core Concept**
Hereditary spherocytosis is a genetic disorder affecting the red blood cell membrane, leading to hemolytic anemia. The underlying principle involves mutations in genes encoding proteins of the red blood cell cytoskeleton, such as **spectrin**, **ankyrin**, and **band 3**. This results in structurally abnormal red blood cells.

**Why the Correct Answer is Right**
The correct answer is related to the genetic basis of hereditary spherocytosis. Most cases are inherited in an **autosomal dominant** manner, meaning a single copy of the mutated gene is sufficient to cause the condition. This is due to mutations in one of the several genes responsible for the structure and function of the red blood cell membrane.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because hereditary spherocytosis does not typically follow an autosomal recessive pattern, which would require two copies of the mutated gene to express the condition.
**Option B:** and **Option D:** are not applicable as the correct inheritance pattern has been identified.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that hereditary spherocytosis often presents with **anemia**, **jaundice**, and **splenomegaly**, and diagnosis can be confirmed by **osmotic fragility testing** and **molecular genetic testing**.

**Correct Answer:** D. Autosomal Dominant.
