Landscape genomics: application in poultry breeding

Code: 9781786767851
Romdhane Rekaya and Samuel E. Aggrey, University of Georgia, USA

Chapter synopsis: Landscape genomics has become an important tool to study the neutral genetic structure of populations and to identify loci and genomic regions under natural or artificial selection. The understanding of the actions of selection on the genome and their association with specific environmental and landscape factors provides an excellent opportunity to further understand the mechanisms involved in natural selection and the possibility for using identified adaptive loci and genome segments in the enhancement of genetic improvement programs of livestock species. This is especially the case for backyard chickens in several developing countries. These local ecotypes are well adapted to their local environmental conditions and landscape genomics could be used to identify and integrate these adaptive loci into sustainable and efficient breeding programs. Continuous decrease in the economic and logistic costs associated with the collection of genomic and environmental information will further favor the implementation of the landscape genomics approach.
