Which of the following is an example of common genetic disorders?

• A. X linked disorders
• B. Genetic diseases
• C. Inherited illnesses
• D. Common genetic disorders

Answer: (D)

Genetic disorders are diseases caused by mutations or abnormalities in the genome. When a group of these conditions occurs with noticeable frequency in populations, we call them common genetic disorders. This choice is the best because it explicitly labels a category defined by how often the conditions appear, which is precisely what “common” signals. The other options describe categories or patterns rather than indicating how frequently the conditions occur: X-linked disorders refer to inheritance via the X chromosome, while genetic diseases and inherited illnesses are broad terms that can apply to many conditions regardless of how common they are. So, emphasizing frequency, common genetic disorders stands out as the clear example.
