Correct reason for Mendel's success was

Options

A. He repeated each experiment several times
B. Traits chosen by him had genes far apart so that linkage was absent
C. He kept record of all experiments
D. He used statistical techniques

Answer

### Step-by-Step Solution

1. **Understanding Mendel's Contribution**:
- Gregor Mendel is known as the father of genetics due to his foundational work on the laws of inheritance. He formulated three key laws: the law of dominance, the law of segregation, and the law of independent assortment.

2. **Analyzing the Options**:
- The question asks for the correct reason behind Mendel's success in his experiments. We need to evaluate each option provided.

3. **Option A - Repeated Experiments**:
- While repeating experiments can enhance reliability, it is not the primary reason for Mendel's success. Therefore, this option is not the correct answer.

4. **Option B - Traits with Genes Far Apart**:
- Mendel selected traits that were located on different chromosomes, which minimized the chances of linkage (genes being inherited together). This absence of linkage allowed him to observe independent assortment, leading to the formulation of his laws. This is a strong reason for his success.

5. **Option C - Keeping Records**:
- Keeping detailed records is essential in scientific research, but it does not specifically explain why Mendel was successful in deriving his laws of inheritance. Thus, this option is also incorrect.

6. **Option D - Using Statistical Techniques**:
- While Mendel did use statistical methods to analyze his results, this alone does not account for his success in understanding genetic inheritance. Therefore, this option is not the correct answer.

7. **Conclusion**:
- The correct reason for Mendel's success is **Option B: the traits chosen by him had genes far apart so that linkage was absent**. This allowed him to derive the laws of inheritance without the complications that linkage would introduce.
