Storyboard Text

  • What if I used pea plants to study more about how traits are inherited from one generation to the next!
  • Parental Generation
  • F2 Generation
  • F1 Generation
  • Parental Generation
  • F1 Generation
  • F2 Generation
  • Gregor Mendel's hypothesis was that the offspring of the pea plants would have a blend of the original pea plants. They would look mixed together. 
  • I'm going to make a new law based on my observations and results of my first experiment. It will state that there are two factors controlling a certain characteristic. One dominates the other. They will separate and go into different gametes when the parent reproduces. 
  • In his first experiment he looked at the flower color. The F1 generation was all purple flowers, and he wondered where the white flower trait had gone. The F2 generation had mostly purple flowers, but did have some white flowers. 
  • WOW! I can make another law based off my findings from my second experiment. It will say that the factors controlling the different characteristics are inherited independently from each other. 
  •  In his second experiment he cross planted yellow round seeds & green wrinkled seeds. The F1 generation had all yellow smooth seeds, but F2 had all possible combinations of the two characteristics. For example, there were green round & yellow rough seeds. 
  • The outcome of Mendel's first experiment was the Law of Segregation
  • As a result of Mendel's second experiment, he created the Law of Independent Assortment. 
  • Mendel's discoveries relate to DNA as he studied genes. Genes are segments of DNA which determine what things look like and why they are the way they are. Gregor Mendel helped learn more about DNA even though that was something unknown. He was very ahead of all other scientists.
