This convenience function finds all genotypes that match a certain target configuration. It is used only if the target configuration contains heterozygous states, but order (e.g., A/B or B/A) does not matter.
Three (three-marker genotypes) or two (two-marker
genotypes) character string specifying the target
configuration. Homozygousity for parent A allele is indicated as
A character vector with all genotypes matching the target
configuration. The format complies with the output format of
