| That's an interesting question, let me show you | |

They move into a small room and start to look at the mouse used for an experiment
|
|
|
|
| | |
| What you're asking about it heredity, the passing down of traits from parent to offspring | |
| | |
|
|
| | |
| Oh yeah we learned about that. Our teacher said that the first born will have the dominant trait, or the stronger trait | |
| | |
|
|
|
|
|
|
|
| | |
| And the trait that shows in the second generation is called the recessive trait | |
| | |
|
 |
| | |
| Exactly! See, these mice have a white mother and a grey father. Since the grey fur is the dominant trait, they will most likely have grey fur | |
