Directions: In the following questions, a statement of assertion (A) ...
Assertion (A): Mendel chose a number of varieties of garden pea as plant material for his experiments.
Reason (R): Garden pea has well-defined characters and is bisexual.
The correct answer is option 'A': Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
Explanation:
Mendel, a famous scientist, conducted experiments on garden pea plants to study the inheritance of traits. He deliberately chose garden pea plants as the material for his experiments due to the following reasons:
1. Well-Defined Characters:
Garden pea plants have distinct and easily observable characteristics or traits. These traits can be categorized into either/or alternatives (such as tall or short, yellow or green seeds, round or wrinkled seeds, etc.). This allowed Mendel to study the inheritance patterns of these traits more easily.
2. Controlled Breeding:
Garden pea plants are bisexual, which means they have both male and female reproductive organs. This allowed Mendel to control the breeding process by manually transferring pollen from the male reproductive organ (anther) to the female reproductive organ (stigma) of the same or different plants. By controlling the cross-pollination, Mendel could ensure that the traits he wanted to study were inherited in a predictable manner.
3. Rapid Reproduction:
Garden pea plants have a short life cycle, and they produce a large number of offspring in a relatively short period. This rapid reproduction allowed Mendel to conduct numerous experiments and collect a substantial amount of data within a reasonable timeframe.
4. Easy Cultivation:
Garden pea plants are easy to cultivate and grow. They can be grown in pots or small plots of land, making them suitable for experiments in limited spaces. Their cultivation requirements are not very demanding, and they can adapt to a variety of environmental conditions.
By selecting garden pea plants as his experimental material, Mendel could easily observe and manipulate their traits, control their breeding, and obtain accurate and reproducible results. The well-defined characters and bisexual nature of garden pea plants provided a solid foundation for Mendel's groundbreaking experiments in the field of genetics.
