Deciphering genetic characteristics of South China and North China indigenous pigs through selection signatures.

ABSTRACT:

Background

Indigenous pig breeds in China have accumulated significant genetic diversity due to regional selection pressures. Investigating the selection signatures of these populations helps to understand their adaptive evolution and contributes to genetic improvement programs.

Results

We collected whole-genome sequencing data from 133 individuals, including South China and North China indigenous pigs and Asian wild boars. After data filtering, we retained 31,521,978 high-quality SNPs. Population structure analysis using PCA revealed distinct genetic clustering among these populations. Selection signature detection identified 5,227 loci under selection in South China indigenous pigs and 5,800 in North China indigenous pigs compared to Asian wild boars. Candidate genes were
