1. AP Biology Mitosis & Meiosis Labs
Natalia Sivackova

2. BACKGROUND INFORMATION
Processes of cell division
2 types
Mitosis: parent cell produces two “daughter” cells that are genetically identical
Meiosis: parent cells divide and produce the gametes that give rise to new individuals

4. LAB 1
“Study the process of mitosis using slides of onion root tips or whitefish blastulae”

5. Cell Cycle Process called karyokinesis: Prophase Metaphase Anaphase
Telophase
Process called cytokinesis

6. Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis

7. Homologous Chromosomes
What genome is composed of
Similar but not identical
Carries same genes in same order
But alleles for each trait might not be the same

8. Synapsis Crossing over (prophase 1) Come together
Sections are exchanged
Both parents

9. LAB 2
“Observing the crossing over in a fungus Sordania”

10. Meiosis occurs in haploid ascospores
Produces spores of different colors
Fertilization occurs when growing filaments meet
Zygotes form
Meiosis occurs in haploid ascospores
