Many pedigree programs compute the percentage of blood for ancestors in the pedigree (PED offered free on these pages for example).  Are you aware that when pigeons are inbred these numbers do not represent the true relationship between the ancestor and the TARGET BIRD!!!  This is because the TARGET BIRD receives common genes from more than one pigeon.  Those pigeons in turn are more\less related to the TARGET BIRD than the percentage blood number indicates.  Examine the Coefficient of Inbreeding and the associated Relationship computations for the sample pairings listed below.
