Description
Jillian is the only non-taster in 3 generations of tasters in her family! How did this happen? In this Mendelian inheritance lab, students will make claims about the bitter taste genotypes of Jillian’s family based on her phenotype as a non-taster, use electrophoresis to test their hypotheses, and construct a Log-Y standard curve to determine the fragment sizes to confirm the fragments are the sizes expected for the 3 different genotypes.
The entire lab can be completed in the span of a single classroom period, and helps teach concepts of inheritance, genetics, physiology, and fragment size analysis using standard curves. Like all our MiniLabs, it allows students to fully engage with the experimental process, from generating a hypothesis, to pouring, loading, and running agarose gels, and analyzing the results. Minimal prep work and clean up give teachers the time they need for lecture and discussion.
Ideal for high school students taking AP Biology.
