In which type of pollination new varieties are not produced?

Explanation

**Step-by-Step Solution:**

1. **Understanding Pollination**: Pollination is the process by which pollen grains from the male part of a flower (anther) are transferred to the female part (stigma) of the same or another flower.

2. **Types of Pollination**: There are two main types of pollination: self-pollination and cross-pollination.
- **Self-Pollination**: This occurs when pollen from the same flower or from another flower on the same plant fertilizes the ovules.
- **Cross-Pollination**: This occurs when pollen is transferred from the anther of one flower to the stigma of a different flower, which can be on the same plant or a different plant.
