As a function of sample size, in absolute number and as a fraction of the size of the living population in Iceland (316,000), (a) the fraction of typed individuals with at least one surrogate parent and (b) the fraction of individuals in the largest connected cluster in the haplotype sharing graph. A person with one or more surrogate parents can at least be partially phased. Individuals in the main cluster have a large number of surrogate relatives, and often every SNP can be phased.
