Whole-genome resequencing reveals the genetic diversity, population structure and selection signatures in Chinese indigenous Kele pigs.

ABSTRACT:

Introduction

Kele pig (KLP) is a valuable Chinese indigenous pig breed, renowned for its strong adaptability, high intramuscular fat content, and excellent meat quality. However, the genomic characteristics of KLPs are still unknown. This study aims to investigate the genetic diversity, population structure, and trait-related selection signatures of KLPs based on whole-genome resequencing.

Methods

The genomes of 30 KLPs were resequenced and analyzed alongside genomic data from 90 pigs of three commercial breeds, comprising 30 Duroc (DUPs), 30 Landrace (LRPs), and 30 Yorkshire pigs (YRPs). To evaluate their genetic diversity, we calculated the expected heterozygosity, observed heterozygosity, polymorphic marker ratio, minor allele frequency, nucleotide diversity (π), runs of
