Trihybrid Cross Calculator – Punnett Square by MarkTrihybrid Cross Punnett Square CalculatorCalculate genotype and phenotype ratios for a trihybrid cross. Trait 1 Name ? Enter name for Trait 1 (e.g., Seed Color). Trait 2 Name ? Enter name for Trait 2 (e.g., Seed Shape). Trait 3 Name ? Enter name for Trait 3 (e.g., Plant Height). Parent 1 – Trait 1 Genotype ? Select genotype (e.g., AA, Aa, aa). AA (Homozygous Dominant)Aa (Heterozygous)aa (Homozygous Recessive) Parent 1 – Trait 2 Genotype ? Select genotype (e.g., BB, Bb, bb). BB (Homozygous Dominant)Bb (Heterozygous)bb (Homozygous Recessive) Parent 1 – Trait 3 Genotype ? Select genotype (e.g., CC, Cc, cc). CC (Homozygous Dominant)Cc (Heterozygous)cc (Homozygous Recessive) Parent 2 – Trait 1 Genotype ? Select genotype (e.g., AA, Aa, aa). AA (Homozygous Dominant)Aa (Heterozygous)aa (Homozygous Recessive) Parent 2 – Trait 2 Genotype ? Select genotype (e.g., BB, Bb, bb). BB (Homozygous Dominant)Bb (Heterozygous)bb (Homozygous Recessive) Parent 2 – Trait 3 Genotype ? Select genotype (e.g., CC, Cc, cc).
