Solution
Break Down the Problem
- Identify the processes of cell division under consideration: mitosis and meiosis.
- Determine the purpose of each process in terms of chromosome number.
Relevant Concepts
- 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.
- 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
- In mitosis, the cell divides once and results in two diploid cells (2n) if the parent cell is diploid (2n).
- 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.
