The activities in Genetics help students to understand basic principles of genetics, including relationships of genotype to phenotype, concepts of recessive and dominant alleles, and how understanding meiosis and fertilization provides the basis for understanding inheritance, as summarized in Punnett squares. The Student Handout includes an analysis of the inheritance of albinism that teaches all of these concepts, a Coin Toss Genetics activity that helps students understand the probabilistic nature of Punnett square predictions, and an analysis of the inheritance of sickle cell anemia that reinforces the basic concepts and introduces some of the complexities of genetics. The Genetics Supplement includes two additional activities, an analysis of student data on the sex makeup of sibships and pedigree analyses of recessive and dominant alleles with challenge questions that introduce the role of mutations and an evaluation of Punnett squares and pedigrees as models of inheritance.
The Teacher Preparation Notes provide instructional suggestions and background information and explain how this activity is aligned with the Next Generation Science Standards.
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 firstname.lastname@example.org.
