The correct Answer is:
To determine the reasons for Mendel's success in his experiments, we will analyze each of the given statements step by step. ### Step 1: Analyze the first statement **Statement (i): His experiments had a large sampling size, thus greater credibility to the data collected.** - Mendel conducted his experiments on a significant number of pea plants, which allowed him to gather a large amount of data. This large sampling size enhances the reliability and credibility of his findings. - **Conclusion:** This statement is correct. ### Step 2: Analyze the second statement **Statement (ii): Use of statistical analysis and mathematical logic.** - Mendel was one of the first to apply statistical methods to biological data. He used ratios to analyze the inheritance patterns of traits, which helped him formulate his laws of inheritance. - **Conclusion:** This statement is also correct. ### Step 3: Analyze the third statement **Statement (iii): Considered many characters at a time.** - While Mendel studied multiple traits (seven contrasting traits), he focused on one trait at a time during each experiment. This approach allowed him to isolate the effects of each trait without interference from others. - **Conclusion:** This statement is incorrect. ### Step 4: Analyze the fourth statement **Statement (iv): Results are confirmed on the successive generation of test plants.** - Mendel did not stop his experiments after one generation; he continued to observe the traits in subsequent generations. This method of confirming results across generations strengthened the validity of his conclusions. - **Conclusion:** This statement is correct. ### Final Conclusion Based on the analysis: - The correct statements that contributed to Mendel's success are (i), (ii), and (iv). - The incorrect statement is (iii). Thus, the answer is **B: First, second, and fourth were the reasons for Mendel's success.** ---

Assertion: During Mendel's investigations into inheritance patterns it was for the first time that statistical analysis and mathematical logic were applied to problems in biology. Reason: Mendel investigated characters in the garden pea plant that were manifested as two opposing traits. e.g, tall or dwarf plants.
