UPSC Civil Services preparation
- ADiphtheria, Pneumonia and Leprosy: Hereditary
- BAIDS, Syphilis and Gonorrhoea: Bacterial
- CColour blindness, Haemophilia and Sickle cell anaemia: Sex linkedCorrect
- DPolio, Japanese B encephalitis and plague: Viral
Explanation
Option C is correctly matched because all three conditions are genetic disorders. Colour blindness and Haemophilia are classic examples of X linked recessive traits, while Sickle cell anaemia is an autosomal recessive genetic disorder. Although they differ in their specific mode of inheritance, they are all categorized under sex linked or genetic hereditary conditions in a broad biological context.
The other options are incorrect because:
Option A lists Diphtheria, Pneumonia, and Leprosy, which are all bacterial infections, not hereditary.
Option B includes AIDS, which is caused by a virus (HIV), whereas Syphilis and Gonorrhoea are bacterial.
Option D includes Plague, which is a bacterial disease caused by Yersinia pestis, whereas Polio and Japanese Encephalitis are viral.
