Solution

Break Down the Problem

  1. Identify the processes of cell division under consideration: mitosis and meiosis.
  2. Determine the purpose of each process in terms of chromosome number.

Relevant Concepts

  1. Mitosis: A type of cell division that results in two daughter cells, each with the same number of chromosomes as the parent cell. It maintains the chromosome number.
  2. Meiosis: A specialized type of cell division that reduces the number of chromosome sets by half, producing gametes (sperm and egg cells) with half the number of chromosomes.

Analysis and Detail

  1. In mitosis, the cell divides once and results in two diploid cells (2n) if the parent cell is diploid (2n).
  2. In meiosis, the cell undergoes two rounds of division (meiosis I and meiosis II), resulting in four haploid cells (n), effectively reducing the chromosome number by half from the original diploid number.

Verify and Summarize

  • Mitosis results in the same number of chromosomes as the parent cell.
  • Meiosis specifically halves the number of chromosomes in the resulting cells.

Final Answer

Meiosis only reduces the number of chromosome sets by half.
