Which of the following geneticits coined the term linkage ?

Options

A. Blakeslee
B. Morgan
C. Muller
D. Bateson and Punnet

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which geneticist coined the term "linkage". This indicates that we need to identify the scientist who first introduced this concept in genetics.

2. **Defining Linkage**: Before identifying the scientist, it is essential to understand what linkage means. Linkage refers to the close association of genes or DNA sequences that are located on the same chromosome. This means that genes that are physically close to each other on a chromosome tend to be inherited together.

3. **Identifying the Scientist**: The question provides a list of geneticists: Blacksley, Morgan, Muller, Batson, and Punnett. Among these, we need to determine who is associated with the term "linkage".

4. **Researching Historical Context**: The phenomenon of linkage was studied extensively by T.H. Morgan, who used the common fruit fly (Drosophila melanogaster) in his experiments. His work laid the foundation for understanding how genes are inherited together when they are located close to each other on a chromosome.

5. **Conclusion**: Based on the understanding of linkage and the historical context, we conclude that the geneticist who coined the term linkage is T.H. Morgan.

**Final Answer**: The correct answer is Morgan.
