Options

A. T.H. Morgan
B. T. Boveri
C. G.Mendel
D. W. Sutton

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Linkage":**
- Linkage in genetics refers to the phenomenon where certain genes are inherited together because they are located close to each other on the same chromosome.

2. **Identifying the Scientist:**
- The term "linkage" was specifically coined by the scientist T. H. Morgan.

3. **Morgan's Experiment:**
- T. H. Morgan conducted experiments using the fruit fly, Drosophila melanogaster, where he performed dihybrid crosses to study the inheritance of two traits simultaneously.

4. **Observation of Linked Genes:**
- During his experiments, Morgan observed that certain genes did not assort independently but were inherited together, indicating that they were linked.

5. **Conclusion:**
- Therefore, the correct answer to the question is that the term "linkage" was coined by T. H. Morgan.
