During reproduction the chromosome nmber (2n) reduces to half (n) in the gametes and again the original number (2n) is restored in the offspring. What are the processes through which these events take place?

Explanation

To answer the question regarding the processes through which the chromosome number (2n) reduces to half (n) in the gametes and is restored to the original number (2n) in the offspring, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding Chromosome Number**:
- In humans, the normal chromosome number is diploid (2n), which means there are two sets of chromosomes (one from each parent).

**Hint**: Remember that diploid (2n) indicates two complete sets of chromosomes.
