1. Mendel’s Laws of Heredity

2. #1 The Rule of Dominance TT T T tt t t Tall plant Short plant All tall plants F1

3. Recessive Traits Dominant Traits Seed shape Seed color Flower color Flower position Pod color Pod shape Plant height roundyellowpurple axial (side) green inflated tall wrinkled greenwhite terminal (tips) yellow constricted short Dominant and Recessive Alleles in Pea Plants

4. #2 The Law of Segregation The law of segregation states that every individual has two alleles of each gene and when gametes are produced, each gamete receives one of these alleles. During fertilization, these gametes randomly pair to produce four combinations of alleles.

6. #3 The Law of Independent Assortment Genes for different traits are inherited independently of each other. – This is why dihybrid crosses work

8. Inheritance project On the front- Mendel’s 3 laws of inheritance – For each: List law name Define in your own words Include a picture On the back-split page in half between codominance and incomplete dominance – For each: Name type of inheritance Define in your own words Include an example Provide a picture At the bottom explain how the two are different

9. Classwork: Provide an example of co-dominance and incomplete dominance. Then explain the difference between the two
