Select parent genotypes or phenotypes to predict possible offspring colors & probabilities
Classic grey is a dominant KIT gene pattern — separate from base color (MC1R/ASIP). All living grey alpacas carry exactly one copy (Gg); no homozygous (GG) alpacas survive. Select each parent's grey status, then also enter their base genotype to see silver vs. rose grey likelihood.
Start watching closely at 330 days. Normal gestation is 335–355 days; due date above is based on 340 days.
Enter your breeding date to calculate your cria's arrival window. Alpaca gestation averages 335–355 days — every female is a little different, so the full range matters as much as the due date.

Color Genotype Predictor
Predict your cria's color using three methods: genotype results (MC1R & ASIP), classic grey inheritance, or visible phenotype. Probability data sourced from Futuregen & Dr. Kylie Munyard research.
