Presentation Transcript

  1. DIPLOID VS. HAPLOID DIPLOID HAPLOID • Diploid = 2(n) • In humans: • n=23 chromosomes • 2(n)= 46 total chromosomes • 2 sets of each chromosomes • Somatic cells are diploid • Body Cells (nerve, muscle, bone, etc.) • Haploid = n • In humans: • n= 23 chromosomes • Only 23 chromosomes total • 1 set of each chromosome • Gametes are haploid • Sex Cells (Sperm & Egg)

  2. Cell Division Mitosis vs. Meiosis

  3. Mitosis Purpose: • For growth and repair • Type of Asexual reproduction for some unicellular organisms

  4. Mitosis Takes place in somatic cells (body cells).

  5. Mitosis Starts diploid (2n) and ends diploid (2n). One cell division

  6. Mitosis One parent makes 2 daughter cells that are identical to the parent No genetic variation

  7. Phases of Mitosis Prophase Metaphase Anaphase Telophase

  8. Meiosis Purpose: • Creation of gametes (reproductive/ sex cells)

  9. Meiosis Takes place in gametes (sexcells).

  10. Meiosis Starts diploid (2n) and ends haploid(n). 2cell divisions

  11. Meiosis • One parent makes 4 daughter cells that are genetically different to the parent • Creates genetic variation • Crossing over of chromosomes is what allows for genetic variation

  12. Phases of Meiosis Prophase I & II Metaphase I & II Anaphase I & II Telophase I & II
