Phenotypes: Eight Dog Breeds

Procedure (cont.)

2. Tell students that they will be investigating hair length and texture in eight different dog breeds. Give each group of students one set of eight Dog Breed Cards. Direct the members of each group to discuss the different kinds of fur or hair that can be observed on the dogs. Use the term “phenotype” when referring to the different observable features of hair. 

3. Direct the groups to sort the eight cards into different categories of fur or hair. They should not use color as a criterion for sorting.

4. After the groups have sorted their cards, allow each group to present or describe the different coat categories they used.
