Question

Which is genetically transmitted trait?

• A. Haemophilia
• B. Muscular dystrophy
• C. Colour blindness
• D. All the above

Answer 1

The correct option is D All the above

• Haemophilia is an inherited bleeding disorder in which a person lacks or has low levels of certain proteins called “clotting factors” and the blood doesn’t clot properly as a result.
• In muscular dystrophies, abnormal genes (mutations) lead to muscle degeneration. Most forms begin in childhood.
• The most common cause of color blindness is an inherited problem in the development of one or more of the three sets of color sensing cones in the eye.

So, the correct answer is 'All the above'.
