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
?

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.
