obsolete unspecified feature true Uses as a term of convenience for describing data reporting unspecified alleles in a genotype (i.e. in cases where zygosoty for a given locus is not known). Typlically recorded in genotype syntaxes as a ' /? '. Not required at present for any specific use case, so marking as exploratory and obsoleting for simplicity. Eq Class def: 'genomic feature' and (has_sequence_attribute some unspecified) An unspecified feature is known to exist as the partner of a characterized allele when the zygosity at that locus is not known. Its specific sequence/identity, however, is unknown (ie whether it is a reference or variant allele). A genomic feature known to exist, but remaining uncharacterized with respect to its identity (e.g. which allele exists at a given gene locus). exploratory term
