Select the incorrect statement for Gregor Mendel-

Options

A. He confducted hybridization experiment on garden pea for seven years.
B. He applied statistical analysis and mathematical logic for the first
time to the problems in biology.
C. His experiments has a small sampling size.
D. He conducted artificial cross-polination experiments using several
true-breeding pea lines.

Answer

To solve the question of selecting the incorrect statement about Gregor Mendel, we will analyze each of the four statements provided.

### Step-by-Step Solution:

1. **Evaluate the First Statement:**
- **Statement:** "He conducted hybridization experiment on garden pea for seven years."
- **Analysis:** This statement is correct. Gregor Mendel conducted his experiments on the garden pea (Pisum sativum) for approximately seven years, from 1856 to 1863.

2. **Evaluate the Second Statement:**
- **Statement:** "He applied statistical analysis and mathematical logic for the first time to the problems in biology."
- **Analysis:** This statement is also correct. Mendel was indeed the first to apply statistical methods to biological data, allowing him to formulate the laws of inheritance.

3. **Evaluate the Third Statement:**
- **Statement:** "His experiments had a small sampling size."
- **Analysis:** This statement is incorrect. Mendel's experiments involved a large number of plants and a significant sampling size, which was crucial for the reliability of his results.

4. **Evaluate the Fourth Statement:**
- **Statement:** "He conducted artificial cross pollination experiments using several true breeding pea lines."
- **Analysis:** This statement is correct. Mendel used various true-breeding lines of peas and employed techniques like emasculation and bagging to perform artificial cross-pollination.

### Conclusion:
The incorrect statement regarding Gregor Mendel is the third statement: "His experiments had a small sampling size."
