Identify the reasons for Mendel’s success.
(a) Application of statistical analysis and mathematical logic to problems in biology
(b) Large sampling size
(c) Usage of true breeding pea plants 
(d) Immense knowledge about linkage

Reasons for Mendel’s success is that he applied statistical analysis and mathematical logic to problems in biology, Large sampling size which gave greater credibility to the data that he collected. One reason for Mendel’s success is that he chose his experimental material, i.e., garden pea astutely.
