Chromosome Band (cytoBand) Track Description
 

Description

The chromosome band track represents the approximate location of bands seen on Giemsa-stained chromosomes.

Methods

Data are derived from the ideogram.gz file downloaded from the NCBI ftp site ftp://ftp.ncbi.nlm.nih.gov/pub/gdp/ (NCBI current version only). Band lengths are typically estimated based on FISH or other molecular markers interpreted via microscopy.
