Flavr Savr variety of Tomato is

Options

A. High yielding hybrid variety
B. High yielding new variety
C. Transgenic
D. Polyploid

Answer

### Step-by-Step Text Solution:

1. **Understanding the Flavr Savr Tomato**: The Flavr Savr tomato is a specific variety of tomato that has been genetically modified. It was developed to have a longer shelf life compared to traditional tomatoes.

2. **Identifying the Options**: The question provides four options:
- High yielding hybrid variety
- High yielding new variety
- Transgenic
- Polyploid

3. **Defining Transgenic**: A transgenic organism is one that has had a foreign gene deliberately inserted into its genome. This is a key characteristic of genetically modified organisms (GMOs).

4. **Historical Context**: The Flavr Savr tomato was the first commercially grown genetically engineered food that was approved for human consumption. It was produced by the Californian company Calgene and received approval from the US Food and Drug Administration (FDA) in 1992.

5. **Mechanism of Action**: The Flavr Savr tomato was engineered by inserting an antisense gene that interferes with the production of the enzyme polygalacturonase. This enzyme is responsible for the softening of the tomato as it ripens, which typically reduces its shelf life.

6. **Conclusion**: By inserting the antisense gene, the Flavr Savr tomato has an extended shelf life due to a slower ripening process. Therefore, it is classified as a transgenic variety, not a hybrid or polyploid.

7. **Final Answer**: The correct option is **transgenic**.
