This track displays simple tandem repeats (possibly imperfect repeats) on the 28 Jan 2021 Cosmia trapezina/GCA_905163495.1_ilCosTrap1.1/GCA_905163495.1 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 274,185 items in the track covering 43,474,293 bases, assembly size 825,187,538 bases, percent coverage % 5.27.
