Seedless fruits can be produced by increase ploidy level. Which of the following ploidy will be better for producing seedless water melon:

Options

A. 3n
B. 4n
C. 2n
D. on

Answer

To determine the best ploidy level for producing seedless watermelons, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Ploidy Levels**:
Ploidy refers to the number of sets of chromosomes in a cell. Common ploidy levels include diploid (2n), triploid (3n), and tetraploid (4n).

2. **Seedless Fruit Production**:
Seedless fruits can be produced by increasing the ploidy level. Higher ploidy levels often lead to seedless varieties in certain fruits.

3. **Watermelon Characteristics**:
Watermelons are typically diploid (2n), which means they have two sets of chromosomes. To produce seedless watermelons, we need to manipulate the ploidy level.

4. **Role of Endosperm**:
In angiosperms (flowering plants), the endosperm is a tissue that provides nourishment to the developing embryo. The endosperm is usually triploid (3n) in nature, formed through the process of double fertilization.

5. **Triploid Endosperm**:
For seedless watermelons, the endosperm needs to be well-developed. A triploid endosperm (3n) is ideal for this purpose because it can develop without the presence of seeds.

6. **Conclusion**:
Therefore, the best ploidy level for producing seedless watermelons is triploid (3n). This is because triploid plants often produce larger fruits and can develop without seeds.

### Final Answer:
The better ploidy level for producing seedless watermelon is **triploid (3n)**.
