Which of the following diseases is not hereditary?

A. Albinism

B. Scabies

C. Haemophilia

D. Colour blindness

QUICK ANSWER…

B

DETAILS…  

Hereditary diseases are those diseases that could be passed from parents and ancestors to offspring.

Now to the right option…

  1. Option A is incorrect; Albinism is a hereditary disorder caused by genetic inability to produce enough melanin for the skin. It can be inherited.
  2. Option B is very correct; Scabies is a skin condition or infestation caused by mite bite, it has nothing to do with heredity.
  3. Haemophilia is a health condition that reduces the ability of blood to clot. Now clotting is necessary for easy healing of wounds. Sadly, the inability for the blood of a Haemophilia patient to clot is caused by a genetic disorder which can be inherited. So, C is incorrect.
  4. Actually, D is also incorrect; color blindness or color vision deficiency is the inability of the eyes to clearly differentiate between colors. Common among men than women, and also inheritable.

QUICK TIPS…
