An illustration of the probabilistic model. This model has three common haplotypes covering four SNPs. In the first step, pairs of the common haplotypes are chosen according to their probabilities α_i. In this example 1,2 and 1,3 are chosen. In the second step, the alleles at each site of the haplotypes are determined according to the probabilities θ_i,j. In the third step, each genotype is formed by a confluence of two haplotypes created at the former step.
