Description
In this single-station kit, students germinate seeds from P1, P2, F1, and F2 generations. They observe the seedlings from P1 and F1 and construct an inheritance pattern model to predict the phenotype and genotype of P2 and what the F2 seedlings will look like. After they examine the actual P2 and F2 seedlings, they can revise their model and explain the results based on the data they collected. The driving question that students investigate is, “How do trait variations in Fast Plants® seedlings reveal inheritance patterns?”
Time Requirement
Planting time is about 20 minutes. The plants will sprout in approximately 72 hours. Scoring and analysis will take approximately 40 minutes.
