Mendelian genetics slides
- 1. Mendelian Genetics How we inherit our genes.
- 2. Gregor Mendel Genetic inheritance was first explained by Gregor Mendel in 1866.
- 3. Why Care? To understand genetic diseases To create new genetic variations To better understand evolution
- 4. How are genetic traits passed on? DNA Transcription RNA Translation Protein ? I think parents pass on their __________ to their offspring DNA Reminder: Draw RNA out overview Protein
- 5. Review
- 6. Review
- 7. How are genetic traits inherited? What kind of cells do you need to make a baby? Gametes: a cell that fuses with another cell during fertilization - Sperm and egg cells - Sex cells Our genetic inheritance is really complicated so let first focus on the simple pea plant.
- 8. Somatic Cells Somatic Cells: Cells that do not participate in sexual reproduction - ex: muscle cells, neural cells, skin cells
- 9. How are genetic traits inherited?: Mendel’s Pea Plant Experiments
- 10. How are genetic traits inherited? Mendel’s Experiment demonstrates the Law of segregation (the first law): parents pass on a randomly selected copy (allele) of a gene to its offspring.
- 11. The second law Law of Independent Assortment: genes for different traits usually will be passed on separately from each other.
