Generate 8×8 Punnett squares instantly for trihybrid crosses. Calculate phenotypic ratios and visualize inheritance patterns for three genes. Free genetics calculator for students and researchers.
Enter the genotypes for two parents. Each genotype should consist of three gene pairs (e.g., AaBbCc, AABBCC, or aabbcc).
Example: AaBbCc represents heterozygous alleles for all three genes. AABBCC is homozygous dominant, and aabbcc is homozygous recessive.
