This track displays simple tandem repeats (possibly imperfect repeats) on the 17 Feb 2021 Ictidomys tridecemlineatus/GCF_016881025.1_HiC_Itri_2/GCF_016881025.1 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 640,624 items in the track covering 40,556,393 bases, assembly size 2,478,965,571 bases, percent coverage % 1.64.
