Figure 1From: Does replication groups scoring reduce false positive rate in SNP interaction discovery?Disease penetrance models. Penetrance models used to simulate epistasis between two SNPs. Allele frequencies are denoted with p and q. For example, model 1 specifies that 10% of individuals with genotypes AABb, AaBB, Aabb or aaBb and none of individuals with other genotypes have the disease.Back to article page
