Description

This track displays simple tandem repeats (possibly imperfect repeats) on the 19 Sep 2018 Xiphophorus couchianus/GCF_001444195.1_X_couchianus-1.0/GCF_001444195.1 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 134,157 items in the track covering 14,719,442 bases, assembly size 688,541,509 bases, percent coverage % 2.14.
