This track displays simple tandem repeats (possibly imperfect repeats) on the 10 Oct 2017 Varroa jacobsoni/GCF_002532875.1_vjacob_1.0/GCF_002532875.1 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 39,880 items in the track covering 2,584,755 bases, assembly size 365,585,945 bases, percent coverage % 0.71.
