Mendel selected pea plant for his experiment bez:- 1)garden pea flowers are normally self pollinated(hybridised), but can be easily cross pollinated its self pollination is prevented. 2)many varieties with distinguished contrasting characters eg,smooth so ed coat. 3)a large no.of progeny can be produced in a short duration. 4)its flower can be easily handled for experimentation.

Reasons for Selecting Pea Plants by Mendel
Mendel’s choice of pea plants (Pisum sativum) for his groundbreaking genetic experiments was influenced by several key factors:

1. Distinct Traits
- Pea plants exhibit clear and easily observable traits such as flower color, seed shape, and pod color. This clarity enabled Mendel to track inheritance patterns efficiently.

2. Controlled Pollination
- Pea plants can be easily cross-pollinated or self-pollinated. This allowed Mendel to control the breeding process and ensure that specific traits were being studied without external interference.

3. Short Generation Time
- The rapid growth cycle of pea plants, which allows them to produce multiple generations in a short span, enabled Mendel to observe and analyze a variety of traits over several generations quickly.

4. True-Breeding Varieties
- Mendel had access to several true-breeding varieties of pea plants. These varieties consistently produced offspring with the same traits, ensuring that any variations observed in the next generations were due to the experimental crosses he conducted.

5. Simplicity of Cultivation
- Pea plants are relatively easy to cultivate and require minimal space, making them practical for Mendel's experiments. This ease of maintenance allowed him to conduct extensive studies without significant resource constraints.
In summary, Mendel’s choice of pea plants was a strategic decision based on their distinct traits, ease of manipulation, rapid generation time, availability of true-breeding varieties, and simplicity of cultivation. These factors collectively made pea plants an ideal model organism for his pioneering work in genetics.
