Which of the following is an Autosomal Dominant disease?
**Core Concept**
The question tests the understanding of **genetic inheritance patterns**, specifically focusing on **autosomal dominant diseases**. Autosomal dominant diseases occur when a single copy of the dominant allele is enough to cause the condition, and they can be inherited from either parent.
**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general principle: An **autosomal dominant disease** is characterized by its ability to be expressed if an individual has one copy of the mutated gene. This means a parent with the disease has a 50% chance of passing it to each offspring.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific disease, it's hard to comment, but typically, an incorrect option would not follow the 50% inheritance pattern or would be associated with a different mode of inheritance.
**Option B:** Similarly, without specifics, this option would likely be incorrect due to not fitting the criteria for autosomal dominance, such as being recessive or linked to a sex chromosome.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **autosomal dominant diseases** often appear in every generation of a family and affect both males and females equally.
**Correct Answer:** Correct Answer: D. Huntington's disease
