Question

Who coined the term 'linkage'?

• A. Henking
• B. W. Sutton and T. Boveri
• C. T.H. Morgan
• D. Tschermak

Hint:

Think of the scientist whose Drosophila experiments first showed genes travelling together.

Answer 1

The Correct Option is C

Understanding the Concept:
Linkage is the tendency of genes located close together on the same chromosome to be inherited together instead of independently.

Check each option:
Henking is known for discovering the X body (later named the X chromosome) in insects, not for the term linkage.
Sutton and Boveri proposed the chromosomal theory of inheritance, linking Mendel's factors to chromosome behaviour, but they did not coin the word linkage.
Tschermak was one of the three botanists who rediscovered Mendel's work in 1900.
T.H. Morgan, working on Drosophila, showed that genes on the same chromosome do not assort independently and introduced the term linkage for this behaviour.

Final Answer:
The term linkage was coined by T.H. Morgan. \[ \boxed{\text{T.H. Morgan}} \]
