About this Event
Uh-oh—there’s been a mix-up in the lab! During an experiment on the genetics of lactase persistence, DNA samples from several “families” got scrambled. Now no one knows which kids belong to which parents!
Here’s the scoop: about one-third of humans can keep digesting milk into adulthood (lactase persistence), while others lose that ability after childhood and may become lactose intolerant. It’s all written in their DNA—but right now, that DNA is a mess. Put on your detective hat and help crack the case! Using real lab techniques and a bit of genetic sleuthing, you’ll track down the right family matches.
Your mission:
- Run agarose gel electrophoresis to uncover the lactase persistence genotypes of each “parent” and “child”;
- Use Punnett squares to predict who could be related to whom;
- Piece together the evidence to match each child with the correct parents;
- Discover how human culture (like dairy farming!) helped shape this genetic trait over time.
Ages 11-14, one adult chaperone required for students under 14. Chaperones must purchase their own ticket and fully participate in all program activities.
