What is Mitosis vs Meiosis process?

Mitosis and meiosis are both processes of cell division, both involve the replication of chromosomes, but they differ in their purposes and outcomes:

  • Mitosis is the process by which a single cell divides into two identical daughter cells, each containing the same number of chromosomes as the parent cell. It is essential for growth, repair, and asexual reproduction.

  • Meiosis is the process that results in the formation of four genetically unique daughter cells, each with half the number of chromosomes of the parent cell. This process is crucial for sexual reproduction and genetic diversity.

  • Venn Diagram: Comparing Mitosis and Meiosis

  • Mitosis occurs in somatic (body) cells and produces two identical daughter cells through one round of cell division, maintaining the same chromosome number as the parent cell (diploid to diploid), with no crossing over. In contrast, meiosis occurs in germ cells (sperm and egg cells) and produces four genetically diverse daughter cells through two rounds of cell division, reducing the chromosome number by half (diploid to haploid) and involving crossing over, which leads to genetic variation.

    • These processes follow similar stages, including prophase, metaphase, anaphase, and telophase, and both start with a diploid parent cell
