How are gametes produced in haploid organisms?

Explanation

**Step-by-Step Solution:**

1. **Understanding Haploid Organisms**:
- Haploid organisms have only one set of chromosomes (n). This means that their cells contain half the number of chromosomes compared to diploid organisms (2n).

2. **Formation of Zygote**:
- In haploid organisms, gametes (sperm and egg cells) fuse during fertilization to form a zygote. The zygote is diploid (2n) because it contains genetic material from both parents.
