This track displays simple tandem repeats (possibly imperfect repeats) on the 04 May 2021 Taeniopygia guttata/GCF_003957565.2_bTaeGut1.4.pri/GCF_003957565.2 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 458,903 items in the track covering 35,139,647 bases, assembly size 1,056,271,262 bases, percent coverage % 3.33.
