Evaluation and refinement of the extended Kosrae pedigree using identity-by-descent estimates.

For each type of relationship, the number of related pairs is shown where the reported relationship and identity-by-descent estimates from genetic data were in agreement (��Confirmed��), conflicting, or added based on genetic data (��Newly discovered��). Estimates for genome-wide IBD sharing and sharing 0, 1, or 2 copies IBD were used to distinguish between the three relationship types. Individuals were added to the pedigree as necessary to represent genetic relationships, such as the addition of a ��placeholder�� father to reflect a newly-discovered maternal half-sib relationship. Corrections to the pedigree were made based on data from related pairs with two genotyped individuals, but impacted relationships throughout the extended pedigree.
