Answer the question briefly in one or two sentence:
During which stage of cell division are spermatids formed from the secondary spermatocytes?

Explanation

**Step-by-Step Solution:**

1. **Understanding Spermatogenesis**: Spermatogenesis is the process of sperm cell development, which begins with a diploid cell known as spermatogonium.

2. **Mitosis to Primary Spermatocyte**: The spermatogonium undergoes mitotic division to produce a primary spermatocyte, which remains diploid.

3. **Meiosis I to Secondary Spermatocyte**: The primary spermatocyte then undergoes meiosis I, resulting in two haploid cells known as secondary spermatocytes.
