Due to the following reasons, Mendel selected garden pea for his experiment:
(i) Garden pea flowers are normally self-pollinated but can be easily cross-pollinated (Hybridized), its self-pollination is prevented.
(ii) Many varieties with distinguished contrasting characters e.g., smooth seed coat, wrinkled seed coat.

ADVERTISEMENTS:
(iii) A large number of progeny can be produced in a short duration.
(iv) Its flowers can be easily handled for experimentation.
Making of True-breeding:
(i) He self-pollinated the pea plants for several successive generation of each variety to eliminate any offspring that was not true to the form of the trait.
ADVERTISEMENTS:
(ii) He ensured that the seeds of a variety produced only that type of plants and so on. For example, the seeds of white flowered plants produced only white-flowered plants in successive generations.
