Mendelian GeneticsHow we inherit our genes.
Gregor Mendel
Genetic inheritance was first explained by Gregor Mendel in 1866.
Why Care?
To understand genetic diseases
To create new genetic variations
To better understand evolution
How are genetic traits passed on?

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.
Somatic Cells
Somatic Cells: Cells that do not participate in sexual reproduction- ex: muscle cells, neural cells, skin cells
How are genetic traits inherited?: Mendel’s Pea Plant Experiments
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.
The second law
Law of Independent Assortment: genes for different traits usually will be passed on separately from each other.
