The example of updating haplotypes in a nuclear family with three offspring for each iteration. In step I, the child #4 was randomly selected to form a trio, and then we updated all three haplotypes in step II. The child #3 was randomly selected in step III and form a new trio with updated haplotypes of parents updated in step II. We repeated the same procedure until all children were selected (step IV to VI)
