Pea plants were more situable than cattle for Mendel's experiment because :-

Options

A. There were no breeding records of cattles
B. Pea plants can be self-fertillsed
C. Cattle are not easy to m.antain
D. All pea plants have 2n chromosomes and fewer genetic traits

Answer

### Step-by-Step Solution:

1. **Identify the Subject of the Question**: The question asks why pea plants were more suitable than cattle for Mendel's experiments.

2. **Recognize the Characteristics of Pea Plants**: Mendel chose pea plants because they exhibit clear and distinguishable traits. For example, traits like flower color and plant height can be easily observed and categorized.

3. **Self-Pollination**: One of the key advantages of pea plants is their ability to self-pollinate. This means that a single pea plant can fertilize itself, allowing Mendel to control the breeding process and study inheritance patterns without the need for external pollinators.

4. **Bisexual Nature**: Pea plants are bisexual, meaning they have both male and female reproductive organs. This characteristic allows them to either self-pollinate or cross-pollinate with other plants, providing flexibility in Mendel's experiments.

5. **Evaluate the Options**: The question likely presents multiple-choice options. Among these, the option stating that "pea plants can be self-fertilized" is the most relevant and correct reason for their suitability in Mendel's experiments.

6. **Conclusion**: Based on the characteristics of pea plants, especially their ability to self-pollinate and their distinguishable traits, it is clear why they were more suitable for Mendel's genetic experiments compared to cattle.

### Final Answer:
Pea plants were more suitable than cattle for Mendel's experiments primarily because they can be self-fertilized, allowing for controlled breeding and clear observation of inheritance patterns.
