1. The problem asks: How many chromosomes does each gamete have after meiosis in humans, given that body cells have 46 chromosomes? 2. Important fact: Human body cells are diploid, meaning they have two sets of chromosomes (46 total). 3. Meiosis is a special type of cell division that reduces the chromosome number by half to produce gametes (sperm and egg cells). 4. The formula for chromosome number in gametes after meiosis is: $$\text{Number of chromosomes in gamete} = \frac{\text{Number of chromosomes in body cell}}{2}$$ 5. Applying this to humans: $$\frac{46}{2} = 23$$ 6. Therefore, each gamete produced by meiosis has 23 chromosomes. 7. This ensures that when two gametes fuse during fertilization, the resulting zygote has the correct diploid number of 46 chromosomes. Final answer: 23 chromosomes.
