The genetic structure and selective sweep analysis of meat pigeon breeds raised in Hainan using whole genome resequencing technology.

ABSTRACT: To investigate the genetic relationships and domestication status of Hainan meat pigeon populations, whole-genome sequencing was performed on 70 individuals across seven breeds: Shiqi (SQ), Silver King (SK), Shenwang (SW), Dabao (DB), Tianxiang No.1 (TX), Hybrid King (HK), and White Carneau (WC), with each breed represented by 10 individuals (5 males and 5 females). From 824 Gb of high-quality sequencing data, we identified 13,347,452 high-confidence single nucleotide polymorphisms (SNPs). Population structure analysis revealed divergent genetic clustering: WC, DB, TX, and HK individuals demonstrated extensive genomic admixture, while SK, SQ, and SW breeds formed distinct clusters with minimal interbreed genetic exchange. Selective sweep analysis highlighted genes under strong positive sel
