Prior Knowledge Questions (Do these BEFORE using
the Gizmo.)
1. The image shows a single litter of kittens. How are they
similar to one another? They all have the same type of
fur, and similar car sizes. (they also have spots)
2. How do they differ from one another? They have different fur colors.
3. What do you think their parents looked like? Their parents probally luok similar to the
Kittens They Might have the same spots
Gizmo Warm-up
Heredity is the passage of genetic information from parents to
offspring. The rules of inheritance were discovered in the 19th
century by Gregor Mendel. With the Mouse Genetics (One Trait)
GizmoT, you will study how one trait, or feature, is inherited.
1. Drag two black mice into the Parent 1 and Parent 2 boxes.
Click Breed to view the five offspring of these parents.
What do the offspring look like? They all (similar have dark to the fur. parents)
The appearance of each mouse is also called its phenotype.
2. Click Clear, and drag two white mice into the parent boxes Click Breed several times. What
is the phenotype of the offspring now? They all have white fur similactor parents
3. Do you think mouse offspring will always look like their parents?
