1 Introduction to Genetics
*What is genetics? Brief History of Genetics *Prehistoric Times: Domesticated Animals/Cultivated Plants (~1000 B.C.)

2 Brief History of Genetics
*The Greek Influence (~ B.C.) Hippocrates – pangenesis Aristotle – “vital heat” *Pre-Mendelian Ideas ( ) Blending Inheritance Epigenesis Preformation *Charles Darwin (1859) Natural Selection *Gregor Mendel (1866) Particulate Inheritance

3 A review of the eukaryotic cell:
Elaborately compartmentalized systems *Generalized animal cell *Generalized plant cell

4 Chromosome duplication and distribution during cell division
Review of terms: *Diploid and haploid *Homologous chromosomes

5 The Mitotic Cell Cycle *Mitotic phase vs. interphase Subphases of interphase: *G1 – first gap *S – synthesis *G2 – second gap

6 Mitosis Late Interphase Prophase Prometaphase

7 Mitosis Metaphase Anaphase Telophase *cytokinesis

8 Cytokinesis: Animal cells Plant cells

9 Mitosis: Animal Cell

10 Mitosis: Plant Cell

11 Sexual vs. Asexual reproduction
“budding”
