Method of imputing the second SNP present in the test haplotype from the four training haplotypes. The “haplotype” column shows the original haplotypes. The “typed” column shows only the SNPs that are typed, the first and the fourth SNP. The “imputed” column shows the haplotypes used in the imputation of the second SNP; only those haplotypes that are identical to the test haplotype on the first and fourth SNP are used in the imputation. A is imputed as of those haplotypes that agreed with the test haplotype on the first and fourth SNP, two haplotypes have an A, and one has a C.
