When a cell with 40 chromosomes undergoes meiosis, each of the four resulting cells has

Explanation

To solve the question, we need to understand the process of meiosis and how it affects the chromosome number in a cell. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Identify the Initial Chromosome Count**:
- The question states that the starting cell has 40 chromosomes.

2. **Understand Meiosis**:
- Meiosis is a type of cell division that reduces the chromosome number by half. It occurs in two stages: Meiosis I and Meiosis II.

3. **Calculate the Resulting Chromosome Count**:
- Since meiosis halves the chromosome number, we need to divide the initial chromosome count by 2.
- Calculation: 40 chromosomes ÷ 2 = 20 chromosomes.

4. **Determine the Number of Resulting Cells**:
- Meiosis results in four daughter cells from one parent cell.

5. **Final Result**:
- Each of the four resulting cells will have 20 chromosomes.

### Conclusion:
When a cell with 40 chromosomes undergoes meiosis, each of the four resulting cells has **20 chromosomes**.
