Step 1:I'll solve this problem step by step:
Step 2:: Understand the key terminology
- Gametes are reproductive cells (sperm or egg cells) - Chromosomes are structures that carry genetic information - Humans have a specific number of chromosomes in their reproductive cells
Step 3:: Recall human chromosome basics
- In human body (somatic) cells, there are 46 chromosomes (23 pairs) - In reproductive cells (gametes), the number is halved to ensure correct chromosome count when fertilization occurs
Step 4:: Determine the number of chromosomes in gametes
- Each gamete (sperm or egg) contains $$23$$ chromosomes
- This is exactly half the number of chromosomes in a normal body cell
Step 5:: Analyze the given options
- Option A: $$23$$ chromosomes ✓
- Option B: 46 pairs of (incorrect) - Option C: 23 pairs of (incorrect) - Option D: 5 (incorrect) - Option E: 46 (incorrect)
Final Answer
Key Insight: During meiosis, the process of gamete formation, the chromosome count is reduced from 46 to 23, ensuring that when fertilization occurs, the resulting zygote will have the standard 46 chromosomes.
