During meiosis, how many times does a single diploid cell divide to produce haploid cells?

• A. Four times
• B. Three times
• C. Once (one division)
• D. Twice (two divisions: meiosis I and meiosis II)

Answer: (D)

Verified step by step guidance

1. Understand that meiosis is a special type of cell division that reduces the chromosome number by half, producing haploid cells from a diploid cell.
2. Recall that meiosis consists of two main stages: meiosis I and meiosis II, each involving a separate division process.
3. Recognize that during meiosis I, homologous chromosomes are separated, reducing the chromosome number from diploid to haploid.
4. Know that meiosis II resembles mitosis, where sister chromatids are separated, resulting in four haploid daughter cells.
5. Conclude that a single diploid cell undergoes two divisions during meiosis to produce haploid cells.
