dna-clip-art.jpgPurpose:
Your task is to explore the world of heredity and its different aspects with the help of this subject sampler. You can do this sampler in pairs or in a small group of three. Visit the list of websites below, try out the various online activities, and complete the questions (10) on a separate sheet of paper. A class discussion based on your findings will be held next class.

A sampler checklist and discussion rubric is provided at the end of the page to help you monitor your work and progress. You are expected to come prepared for the whole class discussion! You may take notes in your lab notebook to help you with your preparation.
