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.
