Mendel selected pea plants for his experiments due to following reasons:
- Pea is an annual plant and hence many generations can be studied in a short duration.
- Pea produces bisexual flowers and hence pure line of homozygous plant can be obtained by self pollination.
- Pea plant can be easily subjected to cross pollination by emasculation.
- Pea plant shows many pairs of contrasting characters which are inheritable.
