mendelian experiments were infact the extension and development of hybridisation experiments on pea conducted by

Options

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

Answer

**Step-by-Step Solution:**

1. **Identify the Context of the Question**: The question asks about the scientists whose hybridization experiments on pea plants were foundational for Mendel's work.

2. **Recall Historical Contributions**: Mendel is known for his experiments on pea plants, which laid the groundwork for the laws of inheritance. However, he built upon earlier work done by other scientists.

3. **Research the Early Experiments**: The early hybridization experiments on pea plants were conducted by two scientists, Knight and Gross, in 1799. Their work was significant but faced limitations due to the lack of resources and knowledge at the time.

4. **Understand Mendel's Contribution**: Mendel began his experiments in the 1860s and expanded upon the findings of Knight and Gross. He formulated the laws of heredity, which describe how traits are inherited from one generation to the next.

5. **Select the Correct Answer**: Based on the historical context, the correct answer to the question is that Mendel's experiments were an extension of the hybridization experiments conducted by Knight and Gross.

**Final Answer**: Knight and Gross.
