The reasons for Mendel’s success are as follows:
1. Mendel studied the inheritance of one character at a time, unlike his predecessors who considered the organism as a whole.
2. The parent plants undergoing crossing belonged to pure lines and had sharply visible contrasting characters.
3. His knowledge in statistics helped him to maintain accurate records of all the experiments of findings and analyzed them carefully.
4. He grew pure lines in separate plots and conducted experiments by crossing two plants from pure strains.
5. He carried out his experiments up to three generations.
6. He selected genetically pure plants for his experimentsg by performing a series of sell crossing tests.
7. All these experiments were conducted with utmost care and meticulous planning.
