Win Punnett

🧬 WHAT IS WIN PUNNETT?

Win Punnett is a genetics tool that builds Punnett squares from parent genotypes and shows the full picture of inheritance. Enter two parent genotypes, tap Build Square, and Win Punnett generates an interactive grid with genotype frequencies, phenotype ratios, and gamete probabilities. Whether you study monohybrid crosses in biology class or work through dihybrid and trihybrid problems, Win Punnett keeps every calculation clear on your screen.

Designed for students, teachers, and anyone studying Mendelian genetics, Win Punnett turns allele notation into visual results you explore with a single tap.

📐 BUILD ANY CROSS

Win Punnett accepts standard allele notation: AA, Aa, aa, AaBb, AaBbCc, and more. Uppercase = dominant allele; lowercase = recessive allele. The app validates input and shows clear messages when genotypes do not match or contain errors.

Supported crosses: monohybrid (single gene), dihybrid (two genes), trihybrid (three genes), test crosses, and pure-line crosses. Both parents must share the same gene loci.

⚡ QUICK PRESETS

Six built-in preset crosses: • Monohybrid F1 — Aa x Aa • Test Cross — Aa x aa • Pure Cross — AA x aa • Dihybrid F2 — AaBb x AaBb • Dihybrid Test — AaBb x aabb • Trihybrid — AaBbCc x AaBbCc

Tap any preset to load genotypes and run the cross. Ideal for homework review, exam prep, and classroom demos.

🔲 INTERACTIVE PUNNETT SQUARE

The result screen shows a full Punnett grid with gamete labels on each axis. Each cell displays the offspring genotype. Tap a cell to highlight all matching genotypes across the grid. Color-coded cells group offspring by phenotype so dominant and recessive patterns stand out.

📊 DETAILED GENETICS ANALYSIS

After each cross Win Punnett provides:

Allele Legend — Dominant and recessive alleles at each locus.

Gamete Probabilities — Each gamete from Parent 1 and Parent 2 with percentages.

Genotype Frequencies — Count and percentage for each unique genotype.

Phenotype Ratio — Simplified ratio (3:1, 9:3:3:1, etc.) plus phenotype percentages.

Expected Offspring Count — Enter total offspring (e.g. 100) for projected genotype counts.

Genotype and Phenotype Probability — Enter a target genotype or check phenotype probability for exact percentage answers.

🕐 RECENT CROSSES HISTORY

Win Punnett saves your last ten crosses on your device. Tap any Recent Crosses entry to reload instantly. Clear history anytime. Your data stays on your phone.

🎨 CLEAN NEON INTERFACE

Dark neon layout with cyan and magenta accents. Large touch targets and readable text make Win Punnett comfortable on phones during study sessions or lab work.
