What genetic condition is characterized by developmental delays and physical disabilities?

• A. Williams Syndrome
• B. Down's Syndrome
• C. Marfan Syndrome
• D. Huntington's Disease

Answer: (B)

Down's Syndrome, also known as Trisomy 21, is a genetic condition that is characterized by both developmental delays and a range of physical disabilities. Individuals with Down's Syndrome typically experience cognitive impairments that can vary from mild to moderate, affecting their learning and development. Physically, they may have distinctive facial features, reduced muscle tone, and other health issues such as heart defects.

This condition arises from the presence of an extra copy of chromosome 21, leading to the developmental and physical challenges associated with it. Early intervention through special education services, therapies, and supportive care often helps children with Down's Syndrome reach their full potential, highlighting the importance of understanding and addressing the needs that accompany this genetic condition.
