Dear Valeria,
A recent related paper is
It may have some useful references.
The main issue in association studies is to create the IBD matrix based on genotyping an incomplete (unknown) pedigree.
The NRM represents the average relationship of an individual with its relatives based on pedigree.
The IBD matrix looks at the specific inheritance of a particular allele at a particular locus.
So far I have not worked on the issue of forming the IBD matrix, just utilising it in ASReml.
May Jesus Christ continue to be gracious to you,
Arthur Gilmour, His servant .
