A hands-on lab where students genotype the LCT gene to discover the evolutionary story behind milk consumption. Connect genotype to phenotype.
Turn your students into genomic researchers. Instead of testing a random sample, your class will use PCR to amplify their own DNA to investigate the genetic switch behind milk digestion. By investigating a single-letter change (SNP) in the LCT gene, students discover exactly how a one-base mutation determines a lifetime of dietary health.
Your students will make the link between their molecular code (genotype) and their daily lives (phenotype). Lead an authentic investigation into human evolution and natural selection, all while mastering the same biotechnology tools used in modern medical testing.

Non-toxic, shelf-stable reagents.
This kit provides the core molecular reagents for this experiment. To see the full list of required lab equipment and consumables (like tips and tubes), view the Materials and Equipment list in the Teacher’s Guide.
Yes, if you have equipment and the other required materials for this number of students. The kit contains enough reagents for up to 40 students.
The Student Lab Guide contains simple step-by-step instructions on how to complete the experiment, so prior PCR teaching experience isn’t essential.
However, we suggest that you learn how to use your specific lab equipment beforehand; ensure that you can use a micropipette; read through the Instructor Guide and Student Lab Guide; and do a practice run before class to ensure you are comfortable with the techniques.
Depending on your lesson and curriculum planning, you might also want to learn and include background information on DNA extraction, PCR, and gel electrophoresis, so you can provide context to the experimental steps done in class.
Preparation should take less than 30 minutes before each class. Some of the preparation, such as making a 0.9% saline solution, programming thermocycler programs, and aliquoting reagents, can be done at any time in advance of the class.
You will need micropipettes, centrifuge/s, a thermocycler, and an agarose gel electrophoresis tank and blue light transilluminator. You will also need plastic consumables and some miscellaneous items described in the Instructor Guide.
Please note that the experiment will work best if there is enough equipment for students to get hands-on with each item of equipment.
