Genetics & Evolution Mission
Trace information from DNA to phenotype — Punnett squares, gene expression, Hardy-Weinberg equilibrium, and molecular evolution.
8 activities · Work through in order for a complete lesson arc
Genetics & Punnett Square Calculator
Generate Punnett squares for monohybrid, dihybrid, incomplete dominance, and sex-linked crosses. Color-coded SVG grid with genotype and phenotype ratios and step-by-step analysis.
DNA/RNA Codon Translator
Transcribe DNA to mRNA and translate codons into amino acid chains. Beautiful sequence diagram with color-coded nucleotides, codon brackets, amino acid pills, full 64-codon table, and reverse translation.
DNA Sequence Explorer
Align DNA sequences with Needleman-Wunsch and Smith-Waterman algorithms. Translate codons, introduce mutations, compute Jukes-Cantor distances, and build UPGMA phylogenetic trees.
Gene Expression Explorer
Simulate lac and trp operon regulation, eukaryotic gene expression, and signal-to-expression cascades. Toggle inducers, repressors, and enhancers to see how transcription rates and protein levels respond.
Hardy-Weinberg Equilibrium Calculator
Calculate allele and genotype frequencies, test populations for HW equilibrium with chi-square, and simulate evolutionary forces like selection, drift, mutation, and migration over generations.
Model how allele frequencies change under selection.
Mitosis & Meiosis Lab
Count cells in different mitotic phases to calculate mitotic index. Estimate phase durations from proportions, compare cell cycle timing, and test phase distribution with chi-square analysis
Hardy-Weinberg & Natural Selection Lab
Simulate allele frequency changes across generations under selection, drift, mutation, and migration. Test Hardy-Weinberg equilibrium with chi-square analysis and explore how evolutionary forces reshape populations
Molecular Evolution Lab
Compare hemoglobin DNA sequences across species. Measure percent identity, compute Jukes-Cantor distances, build phylogenetic trees, and study how mutations affect protein translation
Capstone — compare DNA sequences across species.
