Students would count the kernels (smooth, wrinkled, purple, yellow) and determine if the ears of corn are the result of a dihybrid cross, RrPp x RrPp. This gives students the opportunity to apply statically analysis to data sets and determine if…

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.
