Research progress of domestication and origin in chicken by whole genome sequencing

Abstract

Whole genome sequencing technology started in the middle and late 20th century. In recent years, with the rapid development of high-throughput sequencing technology, the further reduction of sequencing costs and the continuous improvement of assembly methods, it has penetrated into various fields of modern biological research and played a revolutionary role in promoting. Chickens and chicken products have become the necessary means of production and life for people, and chickens are the first species of birds to have the whole genome sequence. In this paper, we reviewed the research progress of whole genome sequencing technology in chicken origin and domestication, especially discussed the significance and problems in the research of candidate genetic signals of chicken breeds.
