has_defining_location Copy number complements represent sets of all copies of a particular biological sequence present in a particular genome. Their "identity" is based on their defining sequence, and the count of this sequence in the genome.The has_defining_location property is used to specify the sequence defining a copy number complement - by using a 'sequence location' as a proxy for a specific sequence that is found at this location. For copy number complements, it is the sequence at this location on some reference that defines sequences in a genome of interest that qualify for membership in the complement. For functional copy number complements (aka genetic dosage), it is the canonical function(s) performed by the sequence at this location (typically that of a gene) that helps to define sequences in a genome of interest that qualify for membership in the complement. Holds between a copy number complement or functional copy number complement, and a genomic location that serves as a proxy for the sequence or functional element that defines the complement. sequence feature location copy number complement functional copy complement
