Q.What are the reasons for Mendel's success in his breeding experiments?

Step 1. Mendel applied mathematics and statistical methods, including the laws of probability, to a biological breeding problem - a rigour no one had previously brought to the study of heredity.

Step 2. He followed careful scientific method, keeping accurate and detailed records that included quantitative data on the outcome of every single cross, rather than relying on casual or qualitative impressions.

Step 3. His experiments were carefully planned in advance and used large sample sizes (he crossed and catalogued 24,034 plants across many generations), which is what let small numerical patterns like the 3:1 ratio emerge clearly rather than being lost in random noise. …
