This track displays simple tandem repeats (possibly imperfect repeats) on the 31 Mar 2021 Cygnus olor/GCF_009769625.2_bCygOlo1.pri.v2/GCF_009769625.2 genome assembly, located by Tandem Repeats Finder (TRF) which is specialized for this purpose. These repeats can occur within coding regions of genes and may be quite polymorphic. Repeat expansions are sometimes associated with specific diseases.

There are 301,579 items in the track covering 15,186,558 bases, assembly size 1,134,186,642 bases, percent coverage % 1.34.
