ASE 2027 Annual Conference

PLEASE NOTE THIS SESSION HAS A MAXIMUM CAPACITY OF 24 - on a first-come, first-served basis on the day (Sched is not used for pre-booking.)

Plants are an ideal model system to teach macro and molecular levels of biology. Anthrocyanins are powerful antioxidants found in many of our favourite produce, including grapes, blueberries and purple cabbage.

In this second session, the molecular evidence comes to life. Taking the PCR products prepared in Part 1, you'll load and run your samples on the MiniOne Electrophoresis System — visualising the DNA banding patterns that reveal the genotype of each plant. Within minutes, the gel tells the story: which plants carry two functional copies of the anthocyanin gene, which carry one, and which carry none.

With results in hand, the real scientific thinking begins. Students will compare their molecular data directly against the phenotypes they scored in Part 1 — connecting the visible purple or green pigmentation of each plant to the genetic evidence on the gel. It's a genuine eureka moment: the bridge between what students can see and what the DNA reveals.

This session brings Mendelian genetics off the page and into the lab in the most tangible way possible. Dominant and recessive alleles are no longer abstract concepts — they are visible bands on a gel, matched to living plants sitting right in front of your students.
