What are the different types of hybridisation?

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Hybridization**: Hybridization is a biological process where two different varieties, species, or genera are crossed to produce a new hybrid. This process is commonly used in agriculture to improve crop varieties.

2. **Types of Hybridization**:
- **Inter-varietal Hybridization**: This type occurs between two different varieties of the same species. For example, crossing two different varieties of wheat to produce a new variety that has desirable traits from both parent varieties.

- **Inter-specific Hybridization**: This type occurs between two different species within the same genus. For instance, crossing two species of the same genus, like different species of the genus *Brassica*, to create hybrids that may have improved characteristics.
