Dog SNPs and Curly Hair
In an effort to add more real data to the DNA (genetics) unit, I added a shortened form of the HHMI activity: “Mapping Genes to Traits in Dogs Using SNPs” The activity on HHMI is too advanced for freshman level biology, but I thought it would be a good introduction to DNA sequences. The activity…

Inquiry in Genetics Using Wisconsin Fast Plants
Genetic Experiments can be intimidating for teachers due to the time and cost of breeding plants or animals in a classroom. These issues are further complicated in a public school setting which may have space issues, limited funds, and lack of access to labs. My favorite model for genetic experiments is the Wisconsin Fast…

Corn Genetics and Chi Square Analysis
Students count kernels on an ear of corn. The corn is the product of a dihybrid cross, so that the phenotype of the kernels will follow a 9:3:3:1 ratio.

Chi Square Analysis
The new Advanced Placement Biology curriculum includes a few topics on statistical analysis under the section on Science Practices: “Students can use mathematics appropriately.” Most introductory level biology classes (freshman) do not include these lessons because it can be difficult with students who haven’t advanced very far in algebra. Seniors in AP Biology should…
