mendelian experiments were infact the extension and development of hybridisation experiments on pea conducted by
(a) Knight only
(b) Goss only
(c) Naudin only
(d) Both Knight and goss

Options

A. Knight only
B. Goss only
C. Naudin only
D. Both Knight and goss

Answer

To solve the question regarding Mendelian experiments and their relation to earlier hybridization experiments conducted on peas, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Mendelian Experiments**:
- Mendel's experiments were groundbreaking in the field of genetics and were primarily conducted on the pea plant, known scientifically as *Pisum sativum*.

2. **Identifying Pre-Mendelian Scientists**:
- Before Mendel's work, there were other scientists who conducted hybridization experiments on peas. The key figures in this context are Knight and Goss.

3. **Knight's Contributions**:
- Knight was known for his work on hybridization in peas, where he studied the inheritance of traits. His experiments laid the groundwork for Mendel's later work.

4. **Goss's Contributions**:
- Similarly, Goss also conducted hybridization experiments that contributed to the understanding of heredity and traits in plants, including peas.

5. **Conclusion**:
- Mendel's experiments can be seen as an extension and development of the work done by both Knight and Goss. Therefore, the correct answer to the question is option (d) Both Knight and Goss.

### Final Answer:
**(d) Both Knight and Goss**
