Which is a better mode of reproduction - sexual or asexual? Why?

Explanation

### Step-by-Step Solution

1. **Definition of Reproduction Modes**:
- **Asexual Reproduction**: Involves a single parent and results in offspring that are genetically identical to the parent (clones). It occurs through processes like mitosis.
- **Sexual Reproduction**: Involves two parents and the formation of gametes (sperm and egg). It includes fertilization (syngamy) and occurs through meiosis.

2. **Process of Gametogenesis**:
- In sexual reproduction, gametes are formed through a process called gametogenesis, which involves meiosis. Meiosis is a reductional division that halves the chromosome number.
