Introduction to Genetics
*What is genetics?
Brief History of Genetics
*Prehistoric Times: Domesticated Animals/Cultivated Plants (~1000 B.C.)
Brief History of Genetics
*The Greek Influence (~400-300 B.C.)
Hippocrates – pangenesis
Aristotle – “vital heat”
*Pre-Mendelian Ideas (1600-1850)
Blending Inheritance
Epigenesis
Preformation
*Charles Darwin (1859)
Natural Selection
*Gregor Mendel (1866)
Particulate Inheritance
A review of the eukaryotic cell:
Elaborately compartmentalized systems
*Generalized animal cell
*Generalized plant cell
Chromosome duplication
and distribution during
cell division
Review of terms:
*Diploid and haploid
*Homologous chromosomes
The Mitotic Cell Cycle
*Mitotic phase vs. interphase
Subphases of interphase:
*G1 – first gap
*S – synthesis
*G2 – second gap
Mitosis
Late Interphase
Prophase
Prometaphase
Mitosis
Metaphase
Anaphase
Telophase
*cytokinesis
Cytokinesis:
Animal cells
Plant cells
Mitosis: Animal Cell
Mitosis: Plant Cell
Sexual vs. Asexual reproduction
“budding”
Overview of meiosis:
Two consecutive cell divisions
*meiosis I
*meiosis II
AKA: Reduction-Division
