Whole-genome resequencing of Dulong Chicken reveal signatures of selection.

Br Poult Sci 2020 Jul 6. Epub 2020 Jul 6.

Key Laboratory for Forest Resources Conservation and Utilization in the Southwest Mountains of China (Southwest Forestry University), Ministry of Education , Kunming, China 650224.

Dulong Chickens (DLCs) live at high altitude (~3000m) and humidity (~90%), which is endemic to Yunnan province, and has gradually developed unique physiological characteristics, but its genetic basis is still unclear. Using the fixation index ( ) approach, based on whole-genome resequencing, DLCs were analysed to uncover the genomic architecture of the population and candidate genes involved in selection during domestication. A total of 469 candidate genes were obtained to be putatively under selection in DLCs. Read More

Identification of potential genomic regions for egg weight by a haplotype-based genome-wide association study using Bayesian methods.

Br Poult Sci 2020 Jun 26;61(3):251-257. Epub 2020 Feb 26.

Department of Animal Sciences, Faculty of Agriculture and Natural Resources, Arak University , Arak, Iran.

1. Theoretically, haplotype blocks might be a more suitable alternative to SNP genotypes as they are usually better at capturing multi-allelic QTL effects, compared to individual SNP genotypes in genome-wide association studies. The objectives of this study were to identify genomic regions related to egg weight traits by Bayesian methods (BayesA, BayesB, and BayesN) that fit fixed-length haplotypes using GenSel software.
