Foal Color Predictor

Predict your foal's coat color probability based on parent colors.

Foal Coat Color Predictor

Calculates genetic allele frequencies and modifier variables

🧬 Sire (Stallion) Color

🧬 Dam (Mare) Color

🧬 Simplified Genetic Engine

Calculates likelihoods based on primary extension gene (E/e), agouti locus (A/a), and dominant dilutes (Cream, Dun, Roan, Grey).

Coat Color Probabilities

⚠️ Note: Equine coat genetics are complex. Environmental factors, unexpressed recessive genes, or white pattern mutations (Sabo, Tobiano) can modify actual phenotypes.
