Banana is seedless because

Options

A. Parthenogenesis
B. Asexual reproduction
C. Triploidy
D. Cross pollination

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks why bananas are seedless. We need to explore the biological reasons behind this phenomenon.

2. **Identifying the Options**: The options provided are:
- Pathogenesis
- Asexual reproduction
- Triploidy
- Cross-pollination

3. **Analyzing the Banana Plant**: Bananas are known to be seedless. This characteristic is primarily due to the genetic makeup of the banana plant.

4. **Triploidy Explanation**: The banana plant is triploid, meaning it has three sets of chromosomes (3n). This triploid condition is crucial because it affects the plant's ability to produce seeds.

5. **Impact of Triploidy on Seed Development**: In triploid plants, even if pollination occurs, the uneven number of chromosomes leads to genetic imbalance. This imbalance causes the seed development process to be arrested, meaning that seeds do not fully develop.

6. **Conclusion**: Therefore, the reason bananas are seedless is due to their triploid nature, which results in the inability to produce viable seeds.

### Final Answer:
Banana is seedless because of its triploidy (3n chromosomal set).
