Selective sweep mapping in the R+ R-chicken lines divergently selected for RFI (residual feed intake)

Résumé

Intense artificial selection of populations leads to the acceleration of evolutionary processes and often results in extreme phenotypes with associated changes across the genome. Selective-sweep mapping makes it possible to identify the genomic regions where allele-frequencies have moved after selection. In this project we performed a selective-sweep mapping in two experimental chicken lines, developed from a common Rhode Island Red base population, by long term divergent selection (40 years) for high (R+) and low (R-) residual food intake, an indicator of feed efficiency.
