GeneForge

A virtual genetics lab: extract the pattern in DNA, predict inheritance, and edit a gene — from Mendel’s peas to CRISPR.

Level 1

For grown-ups — progress report →A private, on-device snapshot mapped to the skill areas practiced. Export a CSV or print — nothing leaves this device.

Punnett Square Builder

Fill the cross grid to predict offspring, then flip it: work backwards from an offspring ratio to name the parents’ genotypes — real inheritance detective work.

Build the crossFill the 2×2 grid, then read the phenotype ratio. Genotype DetectiveGiven the offspring ratio, deduce the parents.

DNA Lab

Build the matching DNA strand, transcribe DNA into mRNA and read the codon chart, or fix a point mutation like a gene editor.

Base pairingA–T and G–C: build the complementary strand. Transcribe & translateDNA → mRNA, then read the codon → amino acid. Gene editorFind and fix the single wrong base.

Same idea, another world

Something you practice here shows up somewhere else too — that's real learning that travels.

A Punnett square is a probability table: the 3-to-1 offspring ratio is favorable outcomes over the total — the same counting behind dice.The shared idea: probability as favorable-over-total — a Punnett square counts favorable offspring over all equally-likely combinations, exactly how you compute any chanceTry ChanceForge →
