Trihybrid and Polyhybrid Cross Calculator
Input genotypes for three independent traits to predict possible genotypic combinations.
Trihybrid and Polyhybrid Cross Calculator
This tool simulates Trihybrid and Polyhybrid crosses, which involve the inheritance of three or more independent genetic traits. It helps visualize Mendelian inheritance in more complex scenarios beyond monohybrid and dihybrid crosses. Free online Punnett square calculator with instant results
What Is a Trihybrid Cross?
A trihybrid cross is a genetic cross that examines the inheritance of three different traits at the same time. Each trait is controlled by a pair of alleles, so a typical trihybrid cross involves parents with genotypes like AaBbCc × AaBbCc.
It follows Mendel’s laws of inheritance and demonstrates how the traits assort independently. Since three traits are involved, the cross produces 64 different genotype combinations and results in a complex variety of 8 phenotypic combinations.
This type of cross helps geneticists predict how multiple traits can be inherited together in offspring.
How This Tool Works
- Enter genotypes for both parents using six-letter combinations (e.g., AaBbCc).
- Each pair of letters represents one trait (e.g., A/a, B/b, C/c).
- Click “Calculate” to view all potential offspring genotypes.

Why Use a Polyhybrid Calculator?
A polyhybrid calculator helps predict genetic outcomes when two or more traits are involved in a cross. It simplifies complex Punnett squares, saves time, and reduces errors in calculating genotypic and phenotypic ratios. This tool is especially useful for dihybrid, trihybrid, and more advanced crosses, making it ideal for students, teachers, and researchers to understand and visualize Mendelian inheritance efficiently.
FAQs – Trihybrid & Polyhybrid Crosses
Can this tool be used for more than 3 traits?
Currently, it’s designed for trihybrid crosses (3 traits). Future updates may include more traits.
Is this tool based on Mendelian genetics?
Yes. It uses principles of independent assortment and dominance from Mendel’s laws.
Can this help in real genetics studies?
Yes! It’s ideal for students, teachers, and anyone studying complex inheritance patterns.
