This track displays simple tandem repeats (possibly imperfect repeats) on the 23 Sep 2019 Drosophila miranda/GCF_003369915.1_D.miranda_PacBio2.1/GCF_003369915.1 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 157,163 items in the track covering 18,977,924 bases, assembly size 287,096,000 bases, percent coverage % 6.61.
