A cell with 46 chromosomes undergoes meiosis. How many chromosomes does each of the four products contain?
Answer: D
Correct answer: 23
Meiosis halves the chromosome number, so a diploid cell with 46 gives four haploid products with 23 each. The halving happens at the first division, when homologous pairs are separated; the second division separates sister chromatids and keeps the number at 23. That reduction is what allows fertilisation to restore 46 rather than doubling it every generation.
