A spermatogonial cell has 30 chromosomes. How many chromosomes will be found in (i) the primary spermatocyte, (ii) a spermatid derived from this cell?

Explanation

To solve the question regarding the number of chromosomes in a primary spermatocyte and a spermatid derived from a spermatogonial cell with 30 chromosomes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Chromosome Number in the Spermatogonial Cell:**
- The problem states that a spermatogonial cell has 30 chromosomes. This means it is diploid (2n), which is the typical state for somatic cells.

2. **Determine the Chromosome Number in the Primary Spermatocyte:**
