The chromosome band track represents the approximate location of bands seen on Giemsa-stained chromosomes.
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.
We would like to thank NCBI for providing this information. Please direct any inquires into the exact method used for each organism to NCBI.
