Information about the continuing improvement of the chicken genome
After the release of Gallus_gallus-5.0 in December 2015, the GRC has taken over the responsibility for the management of chicken reference genome assembly updates. GRCg6a, the latest assembly, has been refined by additional long read sequences, improvements to de novo assembly algorithms, manual annotation of de novo assembled contigs and integration of finished BAC clone sequences. GRCg6a assembly has superior metrics of quality, such as N50 contig size of 18Mb and much lower gap counts. The assembly represents the Red Jungle Fowl strain, inbred line UCD001. All sequences in the assembly are derived from a single individual from this line, female "RJF #256".
