This track displays simple tandem repeats (possibly imperfect repeats) on the 08 May 2019 Populus alba/GCF_005239225.1_ASM523922v1/GCF_005239225.1 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 175,288 items in the track covering 19,871,079 bases, assembly size 416,985,780 bases, percent coverage % 4.77.
