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

**Step-by-Step Solution:**

1. **Understanding Mendel's Work**: Gregor Mendel is known as the father of genetics. He conducted experiments on the inheritance of traits in pea plants (Pisum sativum) to understand how traits are passed from parents to offspring.

2. **Analyzing Statement 1**: The first statement claims that Mendel conducted hybridization experiments on garden pea for seven years (1856 to 1863) and proposed the laws of inheritance. This statement is correct as Mendel did conduct these experiments during this time frame and formulated the foundational laws of inheritance.

3. **Analyzing Statement 2**: The second statement mentions that Mendel experimented with seven characters selected from pure line varieties of pea. This statement is also correct. Mendel worked with seven traits, such as plant height and flower color, and used pure breeding lines for his experiments.

4. **Analyzing Statement 3**: The third statement states that Mendel investigated characters in the garden pea plant that were manifested as more than two opposing traits. This statement is incorrect. Mendel's experiments focused on traits that had only two contrasting forms (e.g., tall vs. dwarf plants), not more than two.

5. **Conclusion**: Based on the analysis, the first two statements are correct, while the third statement is incorrect. Therefore, the option indicating that both statements 1 and 2 are correct is the right answer.

**Final Answer**: The incorrect statement is the third one, which claims that Mendel investigated characters with more than two opposing traits.
