🔍 Dihybrid Cross Calculator 

A Dihybrid Cross Calculator helps determine the genotypic and phenotypic ratios of offspring from two parents with two traits (e.g., seed shape & color). It uses a 4x4 Punnett square based on Mendelian genetics.

✅ Key Features:

• Input: Two parent genotypes (e.g., AaBb x AaBb).

• Output:

  • All possible genotype combinations (like AABB, AaBb, aabb, etc.).

  • Corresponding phenotypic traits (dominant or recessive for each trait).

• Gamete Formation: Produces 4 gametes from each parent using combinations of alleles.

---

🧪 Example:

For parents AaBb x AaBb, typical phenotypic ratio:

• 9 Dominant for both traits

• 3 Dominant for Trait 1, Recessive for Trait 2

• 3 Recessive for Trait 1, Dominant for Trait 2

• 1 Recessive for both traits

So, Phenotypic Ratio = 9:3:3:1

🎯 Use Cases:

• Ideal for biology students, teachers, or anyone learning Mendelian inheritance.

• Useful in predicting trait combinations for two genes (like eye color & height, etc.).
