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

3

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

11

12 End!
