Meiosis

  1. 1. Meiosis One diploid Cell creates 4 haploid cells. Diploid Cell= pairs of similar chromosomes (Humans have 46 chromosomes in 23 pairs) Haploid Cells= does not have pairs of chromosomes (Human has 23 different chromosomes)
  2. 2. Meiosis I Prophase I Metaphase I Anaphase I Telophase I
  3. 3. Meiosis II Prophase II Metaphase II Anaphase II Telophase II
  4. 4. Prophase I Chromatid pairs are visible. Duplicated chromosome pairs come near similar duplicated pairs. Spindle Fiber forms Nuclear memebrane breaks down.
  5. 5. Metaphase I Duplicated chromosomes line up in the middle of the cell next to similar chromosome pair. Spindle fiber connects centrioles to chromosome PAIRS.
  6. 6. Anaphase I Chromosome PAIRS move away from their similar chromosome pair. Spindle fiber pulls the chromosome pairs towards the centrioles
  7. 7. Telophase I Cytoplasm divides Two new cells are formed No nuclear membrane is formed
  8. 8. Meiosis II
  9. 9. Prophase II Chromosome pairs are visible in both cells. Spindle Fiber forms.
  10. 10. Metaphase II Chromosome pairs line up in the middle of the cell. Spindle fiber attaches to each chromosome.
  11. 11. Anaphase II Spindle Fiber separates chromosome pairs into single chromosome Chromosomes are pulled towards the centrioles.
  12. 12. Telophase II Spindle Fiber disappears Nuclear membrane forms around chromosomes Cytoplasm seperates FOUR new cells are formed with two chromosomes each.
  13. 13. Meiosis Ends 4 different haploid cells are made.
