By conducting_____ G. J. Mendel first demonstrate the scientific based of of______.

Options

A. selfing experiments, heredity and variation
B. Hybridisation experiments, chromosomal behaviour of gene
C. hybridisation experiment, inheritance and variation Himachal Bollywood
D. selfing experiments, one gene interaction

Answer

**Step-by-Step Solution:**

1. **Identify the Experiment Conducted by Mendel:**
- G. J. Mendel conducted hybridization experiments using pea plants. He selected specific traits to study how they were inherited.

2. **Understand the Purpose of Mendel's Experiments:**
- The purpose of Mendel's experiments was to demonstrate the scientific basis of heredity. He aimed to understand how traits were passed from parents to offspring.

3. **Recognize the Traits Studied:**
- Mendel studied seven different traits in pea plants, including height (tall and dwarf). He observed how these traits appeared in the offspring through different generations.

4. **Analyze the Results of the Experiments:**
- Through his experiments, Mendel discovered that traits could be dominant or recessive. In the F1 generation, he found hybrids that displayed the dominant trait (tall), while the recessive trait (dwarf) reappeared in the F2 generation.

5. **Conclude the Findings:**
- Mendel concluded that genes are inherited in a predictable manner, leading to the formulation of the laws of heredity. His work laid the foundation for modern genetics.

**Final Answer:**
By conducting **hybridization experiments**, G. J. Mendel first demonstrated the scientific basis of **heredity**.
