Objective: To understand how two traits combine together and how to predict probabilities of what traits offspring will show from the combination. There will be a "traditional" method discussed as well as a "simpler" method.
Monday
Construct a pedigree chart with five generations of families. Determine your own traits and genotypes to put on the pedigree chart.
Tuesday
Begin discussing dihybrid crosses. Use the traditional method. Write out practice problem(s). Here's a video discussing the traditional method of dihybrids:
Wednesday
Review dihybrids using the traditional method. Answer any and all questions from the class. Then show students how to do the "simpler" method. Give a worksheet and allow students to choose which method they want to use.
Thursday
Practice - punnett squares
Friday
Punnett square quiz. Show variations that can exist in genetics such as codominance with blood type, incomplete dominance in snapdragons, etc.
