🧬 Dominant & Recessive Trait Checker 

This handy calculator helps you understand how genes affect traits in living beings.

Every trait is controlled by two alleles—one from each parent. These alleles can be:

• Dominant (shown with uppercase like A)

• Recessive (shown with lowercase like a)

✅ How it Works:

1. You enter two alleles (like A and a).

2. The calculator checks your input.

3. It tells you if the resulting trait will be:

   • Dominant – If there's at least one uppercase letter.

   • Recessive – Only if both letters are lowercase.

🧪 Example:

• Input: A and a → Output: Dominant

• Input: a and a → Output: Recessive

• Input: A and A → Output: Dominant

👶 Why Use It?
