The Genome Reference Consortium

Putting sequences into a chromosome context

The original model for representing the genome assemblies was to use a single, preferred tiling path to produce a single consensus representation of the genome. Subsequent analysis has shown that for most mammalian genomes a single tiling path is insufficient to represent a genome in regions with complex allelic diversity. The GRC is now working to create assemblies that better represent this diversity and provide more robust substrates for genome analysis.

GRCg6a (GCA_000002315.5), the latest chicken reference genome assembly is released.
