Câu hỏi thường gặp
- How do I label traits on the Punnett square?
- Enter dominant and recessive trait names for each gene (e.g. Purple / White for flower color). Leave blank to use default allele-based labels.
- What do the green and pink cell colors mean?
- Green cells show offspring with all dominant traits expressed. Pink cells indicate at least one recessive trait in the phenotype.
- What is a genotype ratio?
- The genotype ratio summarizes how many of each genotype appear in the square, reduced to simplest form (e.g. 1:2:1 for Aa × Aa).
- Can I generate a dihybrid Punnett square?
- Yes. Enter four-allele genotypes like YyRr × YyRr and add trait names for both genes.
- Is my data uploaded?
- No. The square is generated locally in your browser.
