This track displays simple tandem repeats (possibly imperfect repeats) on the 23 Feb 2018 Vanessa tameamea/GCF_002938995.1_ASM293899v1/GCF_002938995.1 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 36,358 items in the track covering 1,999,496 bases, assembly size 357,124,929 bases, percent coverage % 0.56.
