G10 Reproduction

  1. 1. io gyka lo nyi 1 B 0 ol of Tanga de a ional SchKremerGr ernat o MrIn t
  2. 2. Reproduction: Key concepts• Asexual + sexual reproduction + examples• Mitosis + IPMAT• Meiosis + IPMAT x2• Sources of genetic variation
  3. 3. Mitosis
  4. 4. Mitosis + the Cell Cycle Interphase Prophase Metaphase Anaphase Telophase Cytokinesis
  5. 5. Mitosis + the Cell Cycle Interphase Prophase Metaphase Anaphase Telophase Cytokinesis
  6. 6. Mitosis + the Cell Cycle Interphase Prophase Metaphase Anaphase Telophase Cytokinesis
  7. 7. Mitosis + the Cell Cycle Interphase Prophase Metaphase Anaphase Telophase Cytokinesis
  8. 8. Mitosis + the Cell Cycle Interphase Prophase Metaphase Anaphase Telophase Cytokinesis
  9. 9. Meiosis
  10. 10. Meiosis +VariationInterphase as normal 2 divisions Crossing over Haploid gametes Recombination
  11. 11. Meiosis +Variation Prophase 1 Crossing over
  12. 12. Meiosis +Variation Prophase 1 Crossing over
  13. 13. Meiosis +Variation Metaphase 1
  14. 14. Meiosis +Variation Anaphase 1
  15. 15. Meiosis +Variation Telophase 1(sometimes followed by interphase, but not always)
  16. 16. Meiosis +Variation Prophase 2NO crossing over!
  17. 17. Meiosis +Variation Metaphase 2
  18. 18. Meiosis +Variation Anaphase 2
  19. 19. Meiosis +Variation Telophase 2 Produces 4 haploid gametes
  20. 20. Mitosis vs Meiosis Mitosis Meiosis•single division •2 division processes•brief prophase - no crossing over •lengthy prophase includes crossing•produces 2 diploid daughter cells over - more variation•diploid daughter cells genetically •produces 4 haploid gametessame as parent cell •gametes not genetically identical to parent cell
