Total Outcomes: 4. For monohybrid crosses, typical Mendelian ratio is 1:2:1 (Genotype) or 3:1 (Phenotype).
Reference Module v1.0
Blue eyes or brown? The Punnett Square Calculator simulates genetic crosses to predict the probability of traits in offspring.
Drawing 4x4 or 16x16 squares by hand is slow. This tool generates the grid instantly and calculates the Genotype and Phenotype ratios.
Supports Monohybrid (1 trait) crosses
Supports Dihybrid (2 traits) crosses
Calculates Ratios and Percentages
Visualizes Dominant vs Recessive alleles
Mendelian Inheritance assumes traits are determined by independent alleles. Dominant alleles (A) mask recessive alleles (a) unless two recessive alleles (aa) are present.
