Genetics
The activities in Genetics help students to understand the basic principles of genetics, including Punnett squares and pedigree analysis. The understanding of meiosis and fertilization developed in the previous hands-on activity is linked to the understanding of basic principles of genetics. This relationship is demonstrated using model chromosomes in the Student Handout provided below. An alternative version of the Student Handout which uses diagrams instead of model chromosomes is provided in the Teacher Preparation Notes.

We invite comments on this Hands-On Activity and the accompanying Teacher Preparation Notes, including suggestions for other teachers who are planning to use the activity, useful preparatory or follow-up activities, additional resources or any questions you have related to the activity, or a brief description of any problem you might have encountered. If you have a relevant Word document you would like to have posted on this comments page, such as a version of the protocol you have used in your classroom, or if you would prefer to send your comments or questions in a private message, please write Ingrid Waldron at iwaldron@sas.upenn.edu.

January, 2011 revision
The Student Handout now includes a more explicit use of model chromosomes or diagrams to ensure that students understand how meiosis and fertilization result in inheritance and provide the basis for understanding Punnett squares. Numerous additional revisions in the Student Handout and Teacher Preparation Notes are designed to improve understanding of the biology of genetics.
July, 2010 revision
In this revision of the Genetics activity we have modified the coin toss activity so students compare the distribution of genotypes in their families of four "children" with the results for the entire class. The larger sample size provided by using the distribution of genotypes for all of the "children" produced by the students in your class will result in less random variation and a closer approximation to the predictions of the Punnett square. We have made additional, more minor improvements in both the Student Handout and the Teacher Preparation Notes.
