23 pairs of chromosomes can give rise to how many combinations?

Options

A. 8.6 millions
B. 7.6 million
C. 6.6 million
D. 5.6 million

Explanation

To determine how many combinations can arise from 23 pairs of chromosomes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Chromosome Pairs**:
- Humans have 46 chromosomes arranged in 23 pairs. Each pair consists of one chromosome from each parent.

2. **Identify the Haploid Number (n)**:
- The haploid number (n) is the number of chromosomes in a gamete (sperm or egg). For humans, n = 23.

3. **Use the Formula for Combinations**:
- The number of possible combinations of chromosomes that can be produced in gametes is given by the formula \(2^n\), where n is the haploid number.

4. **Calculate the Number of Combinations**:
- Substitute n = 23 into the formula:
\[ \text{Combinations} = 2^{23} \]

5. **Perform the Calculation**:
- Calculate \(2^{23}\):
\[ 2^{23} = 8,388,608 \]

6. **Approximate the Result**:
- The result can be approximated to approximately 8.6 million.

7. **Conclusion**:
- Therefore, 23 pairs of chromosomes can give rise to approximately **8.6 million combinations**.

### Final Answer:
23 pairs of chromosomes can give rise to approximately **8.6 million combinations**.
