Name the scientist who coined the term linkage.

Explanation

**Step-by-Step Solution:**

1. **Understanding Linkage**: Linkage refers to the phenomenon where two genes are located closely together on the same chromosome. This proximity affects how these genes are inherited together during the process of reproduction.

2. **Importance of Linkage**: When genes are linked, they tend to be inherited together more often than genes that are located farther apart on the chromosome. This is because the closer the genes are to each other, the less likely they are to be separated during the process of meiosis.

3. **Identifying the Scientist**: The question asks for the scientist who first coined the term "linkage." This term was introduced based on experiments conducted on fruit flies.
