Population characteristics of typed and untyped individuals in Iceland.

			Expected Number of Typed Individuals Sharing a Specific Locus IBD
			All Relatives		Descendants	Legacy Coefficient

Proband	Ave. YOB	Count	Paternal Allele	Maternal Allele	Paternal/Maternal	Average	Sum
chip typed	1947	35528	17.6	18.1	0.243	0.176	6259
untyped, yob ≥ 1900	1963	375032	16	16.4	0.082	0.054	20130
untyped, 1850 ≤ yob < 1900	1873	101599	14.8	14.8	0.525	0.168	17071

YOB = year of birth. Legacy coefficient is the probability that the paternal/maternal haplotype of an individual is transmitted to at least one typed child or grandchild.
