Predict coat color, gait patterns, and disease risk with real Mendelian genetics. 10,000 Monte Carlo simulations per breeding pair.
From selecting genetics to predicting outcomes — real science, beautiful visualization.
Choose your stallion and mare genotypes. Know the exact alleles? Enter them. Uncertain? We'll use population frequencies for Standardbreds.
Our genetics engine runs 10,000 Monte Carlo offspring simulations using real Extension, Agouti, Grey, Roan, and DMRT3 gait inheritance.
Get coat color probabilities, gait predictions, disease risk assessment, and a genetic compatibility score — all beautifully visualized.
Select genotypes for each parent. "Unknown" uses Standardbred population averages.
