GeneForge

GeneForge teaches inheritance, molecular biology, and biotechnology — a domain with a clean catalogue of named patterns (DNA, alleles, Punnett crosses, mutations, CRISPR edits).

Level 1

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.

Pedigree Detective

Read a family tree — □ male, ○ female, filled = shows the trait — and work out whether a trait is dominant or recessive, who must be a hidden carrier, and each person’s genotype.

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.
