An updated Pig Haplotype Reference Panel (PHARP 4.0) comprising 13,298 haplotypes.

ABSTRACT: High-throughput genome sequencing and genotyping have significantly accelerated genetic research. However, the high cost of whole-genome sequencing (WGS) remains a barrier to large-scale studies like genome-wide association studies (GWAS) and genomic prediction. Genotype imputation offers a cost-effective alternative by inferring unobserved variants from lower-density data using haplotype reference panels. In this study, we present the updated Pig Haplotype Reference Panel (PHARP) 4.0, comprising 6449 pig genomes from 154 breeds. PHARP 4.0 encompasses 50.3 million SNPs and 5.8 million indels, making it the largest and most diverse pig reference panel to date. PHARP 4.0 demonstrated superior imputation accuracy compared to existing panels (SWIM, AHC, AGIDB, and PGRP), achieving concordance
