Penetrance tables of six different models with 3-way interactions. SNP1 has three genotypes AA, Aa, aa and SNP2 has three different genotypes BB, Bb, bb and SNP 3 has three different genotypes CC, Cc, cc. Each cell of a penetrance table represents the probability of being affected given the cell genotype.
