What Do You See?

Procedure (cont.)

3. Display this slide of a litter of puppies and their parent (or print copies of the slide for students to share). Ask students, What do you observe about the puppies in this photograph? Students should notice that several different coat colors and patterns of markings are present. In addition, none of the puppies has the same markings as the mother. Ask, Where did this variation come from? Invite student responses—they should identify the parents (through genetic information, genes, DNA etc.) as the sources of the observed variations in the puppies.
