1. What is a Trihybrid Cross?

A trihybrid cross examines the inheritance of three different traits simultaneously. It follows Mendelian genetics principles and results in 64 possible genotype combinations in the offspring (8×8 Punnett square).

2. How Does the Calculator Work?

The calculator generates all possible gametes from each parent's genotype and combines them in a Punnett square:

For trihybrid crosses (3 traits), each parent produces 8 gametes (2³), resulting in 64 possible combinations.

3. Importance of Trihybrid Crosses

Details: Trihybrid crosses help understand independent assortment, genetic linkage, and the probability of offspring inheriting specific trait combinations.

4. Using the Calculator

Tips: Enter genotypes for both parents using letters (e.g., AaBbCc). The calculator will show all possible offspring genotypes and count unique combinations.

5. Frequently Asked Questions (FAQ)

Q1: How many genotypes are possible in a trihybrid cross?
A: There are 64 possible genotype combinations (8 gametes from each parent).

Q2: What's the phenotypic ratio for a trihybrid cross?
A: For three independently assorting traits with complete dominance, the ratio is 27:9:9:9:3:3:3:1.

Q3: How do I represent linked genes?
A: This calculator assumes independent assortment. For linked genes, specialized tools are needed.

Q4: Can I use this for more than three traits?
A: This calculator is specifically designed for trihybrid crosses (3 traits).

Q5: What if parents have different genotypes?
A: The calculator works with any combination of genotypes for the three traits.
