**Core Concept**
MEN-I (Multiple Endocrine Neoplasia Type I) syndrome is a rare hereditary disorder characterized by the occurrence of tumors in multiple endocrine glands, primarily the parathyroid, pancreas, and pituitary glands. It is caused by mutations in the MEN1 gene, which encodes a tumor suppressor protein.

**Why the Correct Answer is Right**
MEN-I syndrome is inherited in an autosomal dominant pattern, not autosomal recessive. This means that a single copy of the mutated MEN1 gene is sufficient to increase the risk of developing the syndrome. The correct inheritance pattern is crucial for understanding the genetic basis of MEN-I syndrome and for genetic counseling of affected families.

**Why Each Wrong Option is Incorrect**
**Option B:** Hyperparathyroidism is a true association with MEN-I syndrome, as it is one of the most common manifestations of the disorder, often resulting from parathyroid gland tumors.

**Option C:** Islet cell tumors are also a true association with MEN-I syndrome, as they can occur in the pancreas and lead to various endocrine disorders.

**Option D:** MEN-I syndrome is associated with mutations in the MEN1 gene, which is located on chromosome 11, not chromosome 11 itself. This is a crucial distinction, as the location of the gene is relevant to understanding the genetic basis of the disorder.

**Clinical Pearl / High-Yield Fact**
MEN-I syndrome is often associated with a triad of hyperparathyroidism, islet cell tumors, and pituitary tumors, which can lead to a range of clinical manifestations, including hypercalcemia, hypoglycemia, and acromegaly.

**✓ Correct Answer: A. Autosomal recessive**
