Difference Between Mitosis and Meiosis – Simple Guide for NEET 2027
Are you struggling with the difference between mitosis and meiosis? Here’s a clear comparison with stages and important points.
🔥 Hot Points for NEET Aspirants
- Mitosis: Growth and repair → produces two identical diploid cells
- Meiosis: Sexual reproduction → produces four genetically unique haploid gametes
- Meiosis has two divisions but only one DNA replication
Difference Between Mitosis and Meiosis
| Feature | Mitosis | Meiosis |
|---|---|---|
| Definition | Cell division for growth and repair, producing two identical diploid body cells | Cell division for reproduction, producing four genetically unique haploid gametes |
| DNA Replication | Once | Once (before Meiosis I) |
Stages Comparison
Prophase
Mitosis: Chromosomes condense, nuclear envelope breaks down, spindle fibres form.
Meiosis: Prophase I is longer and more complex. Homologous chromosomes pair up (synapsis) and crossing over occurs → genetic variation.
Metaphase
Mitosis: Individual chromosomes align at the equator.
Meiosis I: Homologous pairs align at the equator.
Meiosis II: Similar to mitosis.
Anaphase
Mitosis: Sister chromatids separate and move to opposite poles.
Meiosis I: Homologous chromosomes separate (sister chromatids remain attached).
Meiosis II: Sister chromatids separate.
Telophase & Cytokinesis
Mitosis: Two identical diploid nuclei formed.
Meiosis: Four unique haploid cells formed after Telophase II.
Hope this clears your confusion!
