Teach the Cast
Some of GeneForge’s cast are still learning. When you teach them, YOU learn it best — catch what they get wrong, then quiz them.
Teach Match
You be the teacher — Match is still learning. Helping Match figure it out is the practice. (Only for you; nothing is saved.)
Teach the connections
Show how the genetics ideas connect
You've helped them one at a time. The real understanding is how the ideas CONNECT — teach that next.
Bead (the gene as a discrete inheritable unit) × Match (allele pairing — predicting offspring with Punnett crosses)
A Punnett square predicts exact ratios like 3 to 1. Why do Bead and Match mean the grid works at all?
Bead then says: “Traits blend like mixing paint, which is why Punnett squares give exact ratios.” — is that right?
The link: genes are discrete units, which is exactly what makes the crosses predictable.
Whole units in, predictable ratios out.
Script (the genetic code — DNA to RNA to protein, a recipe) × Snip (mutation and CRISPR — variation and deliberate intervention)
Changing one DNA letter can change how a protein works. Why do Script and Snip explain that?
Script then says: “DNA letters carry no meaning, so editing one has no effect on the resulting protein.” — is that right?
The link: a mutation is an edit to the recipe the code reads into a protein.
Change a letter in the recipe, and the protein can change.
Capstone — predict one trait together
Three genetics ideas. Bring in the cast member for each.
A gene as a discrete unit. Who?
Who do you bring in?
Pair the alleles in a Punnett cross. Who?
Who do you bring in?
Read the recipe from DNA to protein. Who?
Who do you bring in?
The synthesis: discrete genes, predictable crosses, and the recipe from DNA to protein — how a trait is inherited and built.
Unit, cross, and recipe — genetics, understood.
