Question

list 3 differences between mitosis and meiosis.

Explanation:

• Number of Divisions: Mitosis has one division; meiosis has two divisions (meiosis I and meiosis II).
• Chromosome Number in Daughter Cells: Mitosis produces daughter cells with the same chromosome number as the parent cell (diploid to diploid, e.g., in humans \(2n = 46\) to \(2n=46\) for somatic cells). Meiosis produces daughter cells (gametes) with half the chromosome number of the parent cell (diploid to haploid, e.g., in humans \(2n = 46\) to \(n = 23\)).
• Genetic Variation: Mitosis results in daughter cells that are genetically identical to the parent cell (except for mutations). Meiosis results in daughter cells that are genetically diverse due to processes like crossing - over (during prophase I) and independent assortment (during metaphase I).

Answer:

1. Mitosis has one division; meiosis has two.
2. Mitosis: daughter cells same chromosome number as parent (diploid - diploid in many cases); meiosis: daughter cells (gametes) half the chromosome number (diploid - haploid).
3. Mitosis: daughter cells genetically identical (except mutations); meiosis: daughter cells genetically diverse (crossing - over, independent assortment).
