+title: Genome Assemblies and Chromosomes
+description: >-
+  Value sets for reference genome builds (assemblies) and chromosome names/codes for human and
+  common model organisms. Chromosome terms are mapped to the Monochrom Ontology (CHR,
+  https://github.com/monarch-initiative/monochrom), which provides OWL classes for chromosomes
+  and chromosome bands derived from UCSC cytoband files. Genome builds are mapped to their
+  INSDC (GenBank) assembly accessions; the paired RefSeq accession and UCSC database name are
+  given as annotations.
