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

To solve the question, we need to fill in the blanks with the correct terms related to Gregor Mendel's experiments and findings.

1. **Understanding the Context**: Gregor Mendel is known as the father of genetics. He conducted experiments on pea plants to understand how traits are inherited.

2. **Identifying the Experiment**: Mendel's primary method of experimentation was hybridization. He crossed different varieties of pea plants to observe how traits were passed from one generation to the next.

3. **Recognizing the Scientific Basis**: The scientific basis of Mendel's work is centered around the concepts of inheritance and variation. He discovered the fundamental laws of inheritance, which explain how traits are transmitted from parents to offspring.

4. **Filling in the Blanks**: Based on the understanding of Mendel's work:
- The first blank should be filled with "hybridization experiment."
- The second blank should be filled with "inheritance and variation."

Thus, the completed sentence reads: "By conducting hybridization experiment, G. J. Mendel first demonstrated the scientific basis of inheritance and variation."
