🧬 Genotypic Ratio Calculator 

🔹 What It Does

A Genotypic Ratio Calculator predicts the genetic makeup (genotypes) of offspring based on the alleles contributed by both parents. It uses the Punnett square method to calculate the different combinations and count how often each genotype appears.

🔹 How It Works

1. User Inputs: Two parent genotypes (e.g., Aa, AA, or aa)

2. Cross Combinations: It creates all possible combinations of the alleles (4 total for monohybrid crosses)

3. Sorting: Genotypes like “aA” and “Aa” are treated the same (sorted alphabetically)

4. Result: Shows how many times each genotype appears and provides the genotypic ratio

🔹 Use Cases

• 📚 Education: Helps students understand Mendelian inheritance with instant feedback

• 🧪 Genetic Studies: Used in plant/animal breeding for predicting gene expression

• 👨‍👩‍👧‍👦 Family Planning & Awareness: Helps explain potential genetic outcomes in a simplified way

🔹 Key Features

• ✔️ Accepts any two-letter genotype input (Aa, AA, etc.)

• ✔️ Outputs actual genotype combinations (e.g., 1:2:1 ratio)

• ✔️ Easy to integrate into websites, blogs (especially Blogspot/Blogger)

• ✔️ Helps visualize dominant/recessive gene behavior

• ✔️ Useful for classroom demonstrations and online teaching
