Identify in incorrect statements (s) w.r.t Gregor Mendel.

Options

A. Conducted hybridisation experiments on garden pea for seven years (1856-1863) and proposed the law of inheritance in living organisms
B. He experimented with 7 characters selected from 14 pure line varieties of pea
C. Mendel investigated charcters in the garden pea plant that were manifested as more than two opposing traits ?
D. Both (1) & (2)

Answer

To identify the incorrect statements regarding Gregor Mendel, we will analyze the provided information step by step.

### Step-by-Step Solution:

1. **Understanding Mendel's Contribution**:
- Gregor Mendel is known as the father of genetics for his pioneering work on inheritance patterns in pea plants. He conducted systematic experiments to understand how traits are passed from parents to offspring.

**Hint**: Think about why Mendel is significant in the field of genetics.

2. **Mendel's Experimentation**:
- Mendel worked with the garden pea plant (Pisum sativum) for 7 years (1856-1863). He used a large sample size and raised multiple generations to observe inheritance patterns.

**Hint**: Consider the duration and the type of plant Mendel used for his experiments.

3. **Selection of Characters**:
- He selected 7 contrasting characters from 14 pure line varieties of garden peas. These characters were qualitative, meaning they had distinct, non-overlapping traits (e.g., tall vs. dwarf).

**Hint**: Reflect on what contrasting characters mean in the context of Mendel’s experiments.

4. **Contrasting Characters**:
- The characters Mendel studied had only two distinct forms. For example, in terms of height, plants were either tall or dwarf, with no intermediate forms.

**Hint**: Think about how this binary choice simplifies the study of inheritance.

5. **Incorrect Statement Identification**:
- The incorrect statement is that Mendel claimed the characters investigated were expressed in the form of more than two opposing traits. This is incorrect because Mendel specifically chose characters that had only two distinct forms.

**Hint**: Look for statements that contradict the idea of contrasting traits being limited to two options.

6. **Conclusion**:
- The incorrect statement regarding Mendel is that he said the characters were expressed in more than two opposing traits. Therefore, the answer is option C.

### Final Answer:
The incorrect statement regarding Gregor Mendel is option C.
