Gregor Mendel, conducted ________ on garden peas.

Options

A. hybridisation experiments
B. self pollination experiments
C. cytological experiments
D. all of these

Answer

**Step-by-Step Text Solution:**

1. **Identify the Subject of the Question:** The question asks about the type of experiments conducted by Gregor Mendel on garden peas.

2. **Recall Mendel's Work:** Gregor Mendel is known for his pioneering work in genetics, particularly through his experiments with garden pea plants.

3. **Specify the Type of Experiments:** Mendel conducted hybridization experiments. These experiments involved crossing different varieties of garden peas to observe the inheritance of traits.

4. **Duration of Experiments:** Mendel carried out these hybridization experiments over a span of 7 years, from 1856 to 1863.

5. **Publication of Findings:** His findings were published in a paper titled "Experiments on Plant Hybridization," which contributed significantly to the understanding of inheritance.

6. **Selection of Plant Varieties:** Mendel selected 14 true-breeding varieties of garden peas that differed in specific traits, allowing him to study the inheritance patterns of these traits.

7. **Characteristics of Garden Pea Plants:** The garden pea plant (Pisum sativum) was chosen due to its annual nature, short lifespan, ease of cultivation, and the fact that it is a bisexual plant, which facilitated self-pollination and hybridization.

8. **Conclusion:** Therefore, the correct answer to the question is that Gregor Mendel conducted **hybridization experiments** on garden peas.
