Name of the allele for the given gene. All gene-related features (exon, CDS etc) for a given gene should share the same Allele qualifier value; the Allele qualifier value must, by definition, be different from the Gene qualifier value; when used with the variation feature key, the Allele qualifier value should be that of the variant.

Gets the key for this item. These are not necessarily unique within a list, which is why this is a property of an object to be included in a list, rather than omitting this as a property and using a dictionary instead of a list.

A label used to permanently tag a feature.

Gets the location of this feature in the sequence. This may also refers to other genbank files. For example, join(100..200,J00194.1:1..150) In this example location specifies joining of bases from 100 to 200 from the sequence in which this location data present and bases from 1 to 150 from the sequence who's accession number is J00194.1.

Phenotype conferred by the feature, where phenotype is defined as a physical, biochemical or behavioral characteristic or set of characteristics.

Indicates that this feature is a non-functional version of the element named by the feature key.

Gets the dictionary of attributes.
