The reasons for Mendel’s success are:
i. Mendel chose garden pea plant for his experiments which was an annual, naturally self-pollinating plant with several pairs of contrasting characters.
ii. Mendel concentrated only on one character at a time.
iii. He kept accurate records (both qualitative and quantitative).
iv. He used statistical methods for analyzing the results.
v. The characters selected by Mendel were present on different chromosomes.
vi. All the seven pairs of contrasting traits selected by him showed complete dominance.
