Scientific Hypothesis — Definition & Examples

A scientist observed that certain mice in a sample have a gray streak in their fur, and he wanted to find out why. Below are the scientist's notes.

1. Several mice in a random sample have a gray streak in their fur.
2. Sequencing of mice genomes shows that the streaked mice have a mutation where the control group does not.
3. If the mutation is replicated in a normal mouse, it should develop a gray streak.
4. The DNA of the normal mice is mutated to match the DNA of the streaked mice.
5. The newly mutated mice develop a gray streak.
