This track displays simple tandem repeats (possibly imperfect repeats) on the 30 Sep 2020 Passer montanus/GCF_014805655.1_ASM1480565v1/GCF_014805655.1 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 492,684 items in the track covering 41,418,192 bases, assembly size 1,039,966,254 bases, percent coverage % 3.98.
