Complex Traits

Complex Traits

Students use the domestic dog as a model to learn about genetics, DNA, genetic testing, phenotypes, alleles, SNPs, and mutations related to desirable and/or harmful effects in certain dog breeds.

This slide set is designed for use with activities found in Complex Traits Guide for Teachers, a series of six activities.

While the activities are most appropriate for students in grades 6–8, the lessons may be used with higher grade levels.
