Answer

To solve the question regarding the number of gametes formed from the genotype \( PpQq \), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Genotype**: The given genotype is \( PpQq \). This indicates that there are two genes being considered: gene P with alleles \( P \) (dominant) and \( p \) (recessive), and gene Q with alleles \( Q \) (dominant) and \( q \) (recessive).

2. **Determine the Number of Heterozygous Alleles**: In the genotype \( PpQq \), both genes are heterozygous. This means:
- For gene P, the alleles are \( P \) and \( p \) (2 different alleles).
- For gene Q, the alleles are \( Q \) and \( q \) (2 different alleles).

3. **Use the Formula for Gamete Formation**: The number of different gametes can be calculated using the formula:
\[ \text{Number of gametes} = 2^n \]
where \( n \) is the number of heterozygous gene pairs.

4. **Calculate \( n \)**: In this case, there are 2 heterozygous pairs (one from gene P and one from gene Q), so \( n = 2 \).

5. **Calculate the Number of Gametes**: Plugging \( n \) into the formula gives:
\[ \text{Number of gametes} = 2^2 = 4 \]

6. **Conclusion**: Therefore, the total number of different gametes that can be formed from the genotype \( PpQq \) is 4.

### Final Answer:
The answer is **4**.
