This track displays simple tandem repeats (possibly imperfect repeats) on the 21 Feb 2020 Amblyraja radiata/GCF_010909765.2_sAmbRad1.1.pri/GCF_010909765.2 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 1,176,348 items in the track covering 97,024,358 bases, assembly size 2,558,784,953 bases, percent coverage % 3.79.
