Feb 13, 2023 · Chicken is one of the most important vertebrate model organisms, yet its genome is far from complete. This study generated the complete sequence of a chicken genome, uncovering six chromosome models absent in previous genome assemblies.

Jun 25, 2020 · Despite the strong episodic gene flow from geographically divergent lineages of jungle fowls, our analyses show that domestic chickens undergo genetic adaptations that underlie their unique...

Nov 17, 2011 · Researchers estimate that the chicken has about 20,000-23,000 genes in its 1 billion DNA base pairs, compared with the human count of 20,000-25,000 genes in 2.8 billion DNA base pairs. The difference in total amount of DNA reflects a substantial reduction in DNA repeats and duplications, as well as fewer pseudogenes, in the chicken genome.

Mar 27, 2018 · Chicken Genome Overview 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.

May 3, 2023 · Here, we systematically identified and characterized regulatory elements in the chicken genome by integrating 377 genome-wide sequencing datasets from 23 adult tissues. In total, we annotated 1.57 million regulatory elements, representing 15 distinct chromatin states, and predicted about 1.2 million enhancer-gene pairs and 7662 super-enhancers.

To survey its genetic diversity and trace the history of domestication, we investigated a total of 4938 mitochondrial DNA (mtDNA) fragments including 2843 previously published and 2095 de novo units from 2044 domestic chickens and 51 red junglefowl (Gallus gallus).

Here we describe the molecular cytogenetic characterization of each chicken chromosome using chromosome painting and mapping of individual clones by FISH. Where possible, we have assigned the chromosomes to known linkage groups.

Mar 24, 2025 · It’s been 22 years since the chicken became the first agricultural animal to have its genome fully sequenced – a milestone that transformed poultry breeding. By studying a chicken’s DNA, Aviagen can identify qualities that contribute to good health and productivity, such as strong legs, reproductive fitness and healthy growth. These insights allow …

Apr 8, 2025 · The chicken is a major source of protein-rich food. Its unique phylogenetic position, combined with its genetic and physiological characteristics, has established the chicken as a well-recognized ...

Jul 31, 2012 · Comprised of about 1 billion DNA base pairs, the chicken genome is the first avian genome to be sequenced. The Washington University researchers have deposited the initial assembly, which is based on seven-fold sequence coverage of the chicken genome, into the public database, GenBank (www.ncbi.nlm.nih.gov/Genbank).
