HelixQuest
You don’t learn genetics by memorizing ratios — you learn by predicting them. Here you set up a cross, say how the offspring will sort, and a real Punnett-square engine computes it right on your device to check you. Real monohybrid, dihybrid, and test crosses; no hand-waving, nothing sent anywhere, and a wrong guess is the fastest way to see how the alleles actually assort.
The Genetics Bench ★ the main event
Set up a cross, predict the offspring ratio, then watch a pure engine compute the real Punnett square — every box, on your device, no cloud. Monohybrid, dihybrid, and test crosses. The engine computes the exact answer every time, so a missed prediction is just where the genes surprise you.
Zoom out from one cross to a whole population. Predict how an allele or genotype frequency shifts after a generation of selection, gene flow, or Hardy-Weinberg equilibrium — then the bench computes the real p²+2pq+q² next generation. Selection against a recessive, heterozygote advantage (sickle-cell), migration — the population-genetics engine the free tools only let you free-explore.
Predict how a reaction rate responds to substrate concentration, temperature, pH, or a competitive inhibitor — then the bench plots the real kinetics curve on your device. See Michaelis-Menten saturation, the denaturation cliff past the optimum temperature, the pH bell, and why flooding an enzyme with substrate out-competes a competitive inhibitor. The interactive kinetics engine the enzyme kit had only as multiple choice.
Not mascots — working biologists (and a couple of famous ones), each showing a single idea in action. You’ll run into them across the kits and the bench.
Mendel — tracks how alleles assort into offspring ratios (inheritance)
Rosalind — reads the double helix as the molecule that stores the code (DNA structure)
Cyra — copies the genome exactly before a cell divides (mitosis)
Meira — halves and shuffles the genome to make variation (meiosis)
Sol — captures light energy into sugar (photosynthesis)
Otto — releases the energy stored in sugar (cellular respiration)
Darwin — lets the fittest variants leave more offspring (natural selection)
Vera — keeps the internal balance steady against change (homeostasis)
Cat — speeds a reaction without being used up (enzymes)
Dr. Okafor — the mentor — predict the outcome, run the model, then reconcile
Check what you know
Sixteen short kits — from Mendelian genetics and cell structure to photosynthesis, respiration, DNA, mitosis, meiosis, gene expression, evolution, ecology, homeostasis, and enzymes — anchored to high-school biology. Hints when you want them; your progress stays on this device.
HelixQuest is written to trust you — it’s about reasoning through how genes behave, not memorizing ratios, and a wrong prediction is just a place to learn. The Genetics Bench is a small, exact engine: no server, nothing sent anywhere. Your progress is saved only on this device: no accounts, no ads.
