Genetics and Evolution vs Genetics Lab

Genetics and Evolution solves four types of basic problems commonly taught in introductory genetics courses in high schools and colleges. This app was originally designed for the Duke University (and Coursera) Introduction to Genetics and Evolution course, but it is helpful for any students, teachers, or practitioners in genetics! Problems solved include: * Genetic cross mapping -- accepts genotype counts for three genes from a "test cross", and uses the counts to infer the gametic phase, the recombination rate between the three genes, and the gene order. * Breeder's equation heritability -- with any three of the following values, calculates the fourth: starting phenotype, selected phenotype, response phenotype, broad-sense heritability. * Hardy-Weinberg -- accepts genotype counts for a single gene and outputs observed genotype frequencies, expected genotype frequencies, and the coefficient of inbreeding (F). * Population Growth -- with any of the following 3 values, calculates the fourth: Initial Population, Final Population, Time in years, Growth Rate (or separate birth/death rates) * Self Test quiz-- quiz yourself on some common basic genetic terms. * Allele Freak: track and graph the fate of alleles over multiple generations based on relative fitness, genetic drift etc * Cross Simulator: simulate various types of Mendelian crosses. results are displayed in Punnett Square format, and resulting genotypes/phenotypes and ratios are displayed Use this app to check your answers, or better yet, to generate a nearly infinite number of practice problems! Features Dropbox integration for depositing a pdf of practice problems.

Turn DNA, alleles, and heredity from a page of vocabulary into something you can actually see, build, and breed. Genetics Lab is an interactive biology lab where every lesson ends with your hands on a Punnett square, a genotype, or a living 3D creature — not a multiple-choice quiz you forget by tomorrow. Instead of memorizing terms, you breed a fictional creature called the Glimmerbeast across 15 traits and roughly 41 alleles, watching its coat, eyes, ears, wings, horns, and more change in real time as Mendelian genetics plays out on screen. Every cross you run is a real Punnett square with a real, calculable outcome — no human genetics, no medical framing, just a safe sandbox for experimenting with heredity. WHAT YOU'LL LEARN — 4 WORLDS, 34 LESSONS • World 1, Mendel Basics — genes vs alleles, dominant & recessive traits, genotype vs phenotype, the monohybrid cross, the Punnett square, and reading offspring ratios • World 2, Dihybrid & Probability — crossing two traits at once, independent assortment, the 9:3:3:1 ratio, the product rule, the sum rule, test crosses, and probability branch diagrams • World 3, Beyond Mendel — incomplete dominance, codominance, multiple alleles, and sex-linked inheritance: the patterns real biology actually uses beyond the textbook basics • World 4, Population Genetics — allele frequencies, the Hardy-Weinberg equation, DNA structure, and mutation Each lesson breaks a concept into short, interactive steps with instant feedback, so you build real intuition for genotypes and phenotypes instead of just memorizing a Punnett square shortcut. THE BREEDING LAB & 3D DNA BUILDER • Cross Lab — pick parent genotypes across all 15 loci and watch Mendelian inheritance, incomplete dominance, and codominance resolve into a real offspring; every result is mathematically correct, never random • DNA Lab — an interactive 3D DNA builder and visualizer that turns the double helix, base pairing, and chromosomes into something you can rotate and explore, instead of a flat diagram in a textbook • Collection — 120 breeding challenges that ask you to hit specific genotype and phenotype targets: a two-trait cross, a rare recessive combination, a sex-linked pattern, and more, unlocking every creature variation as you go AI GENETICS TUTOR Stuck on why a cross gave you a 3:1 ratio instead of 1:1? Ask the built-in AI tutor to explain any genotype, cross, or ratio in plain language, tailored to the exact problem in front of you. WHO IT'S FOR Built for high school and college biology students working through Mendelian genetics and heredity, homeschool learners who want a hands-on lab without a real one, and anyone who wants DNA, alleles, and probability to finally click. No prior biology background required — Genetics Lab starts at "what is a trait?" and builds up from there, one Punnett square at a time. WHY GENETICS LAB • Every concept is interactive, not a slideshow — you run the cross, read the Punnett square, and see the outcome • A complete curriculum in one app: Mendelian basics through dihybrid crosses, non-Mendelian patterns, and population genetics • A real 3D DNA visualization tool, not just static illustrations • Progress tracking across all 4 worlds so you always know what lesson is next • A free-play Sandbox lab to experiment with alleles and traits beyond the lesson plan • Ads shown to support free content; go ad-free anytime with Pro GENETICS LAB PRO Subscribe to unlock every world and lesson, all 15 traits for breeding, the full 120-challenge Collection, the AI genetics tutor, and an ad-free experience. Choose monthly or annual billing, with a free trial available on the annual plan — manage or cancel anytime in your account settings.
