From: Typing without calling the allele: a strategy for inferring SNP haplotypes
Levels of genetic information. The spectrum of levels of genetic information of an individual, depicted along a 6-SNP region: full haplotype sequences provide full information (including previously unknown SNPs); SNP haplotypes separate the alleles at known SNP sites into the two chromosomes; genotypes provide only the confluence of the allele identities at each SNP site, and xor-genotypes (introduced here) only tell which sites are heterozygous. Arrows indicate that haplotypes are computationally inferred from genotypes, and can also be computationally inferred from xor-genotypes by a process called xor-haplotyping (as shown in this work). Information decreases from full haplotype sequencing to xor-genotype determination (top). Costs diminish from full haplotypes to genotypes, and may potentially decrease further if only xor-genotypes are measured (bottom).
