The major advantages of selecting pea plant for experiment by Mendel are as follows:

i. Pea plant has 7 contrasting characteristics which can be phenotipically distinguished.

ii. Every contrasting character has only 2 alleles and none of them are linked.

iii. The plant undergoes self pollination thus easily produces the offsprings with same traits generation after generation.

iv. Due to self pollination homozygous plants can be obtained easily.

v. Cross pollination for experimentation can be easily performed by emasculating the stamen of the flower without affecting the flower.

vi. They have a short life span and produce many seeds at a time.
