Linkage was first studied by :-

Options

A. Darwin
B. Morgan
C. Bateson and Punnett
D. Mendel

Answer

To solve the question "Linkage was first studied by:", we can follow these steps:

### Step 1: Understand the concept of linkage
Linkage refers to the phenomenon where two or more genes located on the same chromosome are inherited together during meiosis. This means they do not assort independently.

### Step 2: Identify the key figures in genetics
The question provides several names: Darwin, Morgan, Bateson, and Mendel. Each of these scientists contributed significantly to the field of genetics, but their contributions vary.

### Step 3: Review historical context
- **Darwin** is known for his theory of natural selection but did not study linkage.
- **Mendel** is recognized as the father of genetics for his foundational work on inheritance patterns, but he did not specifically study linkage.
- **Morgan** conducted experiments with fruit flies (Drosophila) and provided evidence for the linkage theory later on.
- **Bateson and Punit** were the first to study linkage in detail through their work with sweet peas in 1906.

### Step 4: Conclude with the correct answer
Based on the historical context and contributions of these scientists, the correct answer to the question is **Bateson and Punit**, as they were the first to study linkage in 1906.

### Final Answer:
Linkage was first studied by Bateson and Punit.
