The correct Answer is:
**Step-by-Step Text Solution:** 1. **Definition of Albinism**: Albinism is a genetic disorder characterized by a deficiency of the pigment melanin in the body. 2. **Role of Melanin**: Melanin is responsible for the pigmentation of the skin, hair, and eyes. In individuals with albinism, the lack of melanin results in very light skin, often appearing almost white. 3. **Cause of Albinism**: The deficiency of melanin occurs due to a lack of functioning melanocytes, which are the cells responsible for producing melanin. 4. **Biochemical Pathway**: Melanin is synthesized from the amino acid tyrosine through the action of the enzyme tyrosinase. In albinism, there is a deficiency or malfunction of this enzyme. 5. **Genetic Basis**: The gene responsible for producing tyrosinase can be defective due to mutations. This genetic defect is inherited in a recessive manner, meaning that an individual must inherit two copies of the mutated gene (one from each parent) to express the condition. 6. **Conclusion**: Therefore, albinism is classified as a genetic disorder, not an environmental disorder, deficiency disease, or infectious disease. 7. **Correct Answer**: Based on the above explanation, the correct answer to the question "Albinism is" is that it is a genetic disorder. ---
