||A related sequence or allele contains stable mutations from the same gene (e.g., RFLPs, polymorphisms, etc.) which differ from the parent sequence at the given location;
||used to describe alleles, RFLP's,and other naturally occurring mutations and polymorphisms; variability arising as a result of genetic manipulation (e.g. site directed mutagenesis) should be described with the misc_difference feature;use /replace=\"\" to annotate deletion, e.g.variation 4..5 /replace=\"\"
||#* The frequency of this variation within the population
