Scientific Method

The Scientific Method is the term used to define the process used by scientists to obtain information. The problem solving portion of Genetics is an ideal place to apply the process to our studies.

1. Observe some aspect of the universe. Observe results of a genetic crosses.
2. Invent a theory that is consistent with what you have observed. Develop a theory to describe your observations - [for example a single gene dominant or recessive]
3. Use the theory to make predictions. Choose a Null Hypothesis H0 and an Alternative Hypothesis H1
4. Test those predictions by experiments or further observations. Design an experiment to test the hypothesis.
5. Modify the theory in the light of your results. Accept or Reject your hypotheses ie. reject the null hypothesis and accept an alternative hypothesis.
6. Go to step 3.
