🔬 Phenotypic Ratio Calculator – Overview

A Phenotypic Ratio Calculator helps determine the observable traits (phenotypes) of offspring based on the genetic makeup (genotypes) of the parents using Mendelian inheritance principles.

---

✅ Key Features:

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

• Process:

  • Builds a Punnett square.

  • Analyzes resulting genotypes.

  • Determines whether each genotype expresses the dominant or recessive phenotype.

• Output: A simplified phenotypic ratio, e.g., 3 Dominant : 1 Recessive.

---

🧬 Example:

For parents Aa x Aa:

• Genotype combinations: AA, Aa, aA, aa

• Phenotypes:

  • AA, Aa, aA → Dominant

  • aa → Recessive

• Phenotypic Ratio = 3 Dominant : 1 Recessive

🎯 Uses:

• Great for biology students, teachers, or anyone studying genetics.

• Demonstrates the principles of inheritance and how traits are expressed.

• Useful in understanding real-life examples like eye color, flower color, or disease inheritance.
