Analysis of the genetic structure and selection signatures of Xiangyang black pigs using whole-genome resequencing data.

ABSTRACT:

Background

Xiangyang Black (XYB) is a valuable indigenous pig breed from Hubei Province, China, known for its high meat quality, disease resistance, and adaptability to the local conditions. To explore the genetic diversity, population structure, and selection signatures of XYB in the context of Chinese and Western pig breeds, we performed whole-genome resequencing on 15 pig breeds, involving 225 individuals.

Results

After quality control, 20,479,203 high-quality single-nucleotide polymorphisms (SNPs) were retained for subsequent analysis. Genetic diversity analysis revealed that XYB exhibited relatively high genetic diversity, with an observed heterozygosity (Ho) of 0.38 and a nucleotide diversity (pi) of 0.35 and the inbreeding coefficient based on runs of homozygosity (F<
