Which of the following conditions is NOT hereditary?

1. Migraines

2. Diabetes

3. Nystagmus

4. Conjunctivitis

The correct answer is: Conjunctivitis

Conjunctivitis is the correct choice as a condition that is not hereditary. It is primarily an inflammatory response of the conjunctiva, typically caused by infections (such as viral or bacterial), allergens, or irritants. While some individuals may have a genetic predisposition to allergies that could lead to allergic conjunctivitis, the condition itself is often triggered by environmental factors rather than an inherited genetic trait. In contrast, conditions like migraines, diabetes, and nystagmus can have a hereditary component. Migraines have been shown to run in families, suggesting a genetic influence. Diabetes, particularly Type 2 diabetes, has established hereditary risk factors, as family history plays a significant role in its development. Nystagmus can also be hereditary, often linked to genetic conditions that affect eye function. Understanding this distinction is crucial for recognizing how genetics can affect different health conditions.
