Mention the contribution of Gregor Mendel ? Mention the reasons for his success.

Gregor Mendel, conducted hybridisation experiments on garden peas for seven years ($1856$-$1863$) and proposed the laws of inheritance in living organisms.

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.

His experiments had a large sampling size which gave greater credibility to the data that he collected.

Also the confirmation of his inferences from experiments on successive generations of his test plants, proved that his results pointed to general rule of inheritance rather than being unsubstantiated ideas.

Mendel investigated characters in the garden pea plant that were manifested as two opposing traits e.g. tall or dwarf plants, yellow or green seeds.

This allowed him to set up a basic framework of rules governing inheritance, which was expanded on by later scientists to account for all the diverse natural observations and the complexity inherent in them.

Mendel conducted such artificial pollination/cross pollination experiments using several true breeding pea lines.

A true - breeding line is one that having undergone continuous self pollination, shows the stable trait inheritance and expression for several generation.

Mendel selected $14$ true-breeding pea plant varieties as pairs which were similar except for one character with contrasting traits.
