This field is used to identify pairs of participants who are estimated to be genetically related.
Because each set of data distributed to researchers is anonymised differently it is impractical to provide an individually customised list of related participants IDs. Instead, each pairing of related participants is assigned a unique number, and the pairings can be reconstructed by identifying participants who share the same number.
The strength of the inferred relationship is indicated in Field 22012 and Field 22013.
