Options

A. Artificial selection
B. Domestication
C. Both (1) & (2)
D. Mutation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the development of Sahiwal cows in Punjab. We need to identify the methods used for their development.

2. **Identifying Sahiwal Cows**: Sahiwal cows are a breed of cattle known for their high milk yield. They are primarily found in Punjab, India, and Pakistan.

3. **Methods of Development**:
- **Artificial Selection**: This is a process where specific traits are selected for breeding. In the case of Sahiwal cows, traits that lead to high milk production were selected.
- **Domestication**: This refers to the process of adapting wild animals for human use. Sahiwal cows were domesticated from wild cattle, allowing them to be raised under human supervision.

4. **Evaluating the Options**:
- **Artificial Selection**: This is correct as it was used to enhance desirable traits in Sahiwal cows.
- **Domestication**: This is also correct as Sahiwal cows were domesticated from wild ancestors.
- **Both One and Two**: Since both artificial selection and domestication contributed to the development of Sahiwal cows, this option is also correct.
- **Mutation**: This is incorrect as mutation refers to changes at the genetic level, which were not the basis for developing Sahiwal cows.

5. **Conclusion**: The correct answer to the question is "both one and two," as Sahiwal cows were developed through both artificial selection and domestication.

**Final Answer**: Sahiwal cows of Punjab are developed by both artificial selection and domestication.
