This track displays simple tandem repeats (possibly imperfect repeats) on the 15 Apr 2021 Erannis defoliaria/GCA_905404285.1_ilEraDefo1.1/GCA_905404285.1 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 131,342 items in the track covering 14,219,358 bases, assembly size 522,369,616 bases, percent coverage % 2.72.
