Founders (having unknown sire and dam) that appear only one time in a pedigree are uninformative and can be removed from a pedigree without loss of information.
Examples
examplePedigree <- nprcgenekeepr::examplePedigree
breederPed <- qcStudbook(examplePedigree, minParentAge = 2,
reportChanges = FALSE,
reportErrors = FALSE)
probands <- breederPed$id[!(is.na(breederPed$sire) &
is.na(breederPed$dam)) &
is.na(breederPed$exit)]
ped <- getProbandPedigree(probands, breederPed)
nrow(ped)
#> [1] 704
p <- removeUninformativeFounders(ped)
nrow(p)
#> [1] 509
p <- addBackSecondParents(p, ped)
nrow(p)
#> [1] 690
