Which type of cell division is responsible for creating variations in a species?

Explanation

**Step-by-Step Solution:**

1. **Understanding Cell Division Types**: There are two main types of cell division: mitosis and meiosis. Mitosis is responsible for growth and tissue repair, while meiosis is involved in the production of gametes (sperm and eggs).

2. **Mitosis Overview**: Mitosis is an equational cell division where one mother cell divides to produce two identical daughter cells. Both the mother and daughter cells have the same diploid number of chromosomes (2n). This means there is no variation in the genetic material.

3. **Meiosis Overview**: Meiosis, on the other hand, is a reductional cell division. A single mother cell with a diploid number of chromosomes (2n) undergoes two rounds of division to produce four daughter cells, each with a haploid number of chromosomes (n).
