1. Mendelian Genetics

2. Gregor Mendel Austrian monk “Father of Genetics”
Bred thousands of pea plants
Described how traits are passed between generations

3. Mendel’s Experiment
Worked with pea plants because they reproduce quickly and he could control their reproduction
Followed seven traits: pea shape, pea color, pod shape, pod color, plant height, flower color, and flower position

4. Results Cross- the mating of two organisms
Mendel crossed pea plants and observed the ratio of traits present in the second (F2) generation

5. Results

6. Conclusions Law of segregation
Organisms inherit two copies of each gene, one from each parent.
Organisms donate one copy of each gene to their gametes. The two copies of each gene segregate (separate) when gametes are formed.
