Haplotypes for phased genotypic information are determined from unphased
genotypic information. One exemplary method includes separating a dataset that
includes genotypic information for a plurality of markers for each of a plurality
of individuals into subdatasets, each subdataset including the genotypic information
for a subset of the plurality of markers; for each subdataset, identifying haplotypes
compatible with marker information for each marker of the subset and for each individual
of the plurality; and for each individual, assembling the haplotypes from each
of the subsets to provide the individual's haplotype with respect to the plurality
of markers.
