Molecular Pedigree Construction and Inbreeding Assessment of Hanjiang Black Pig
摘要
Abstract
This study aims to elucidate the pedigree structure and degree of inbreeding among Hanjiang black pigs,providing essential research insights for the development of genetic breeding and breeding pro-grams.Whole genome resequencing was conducted on 60 Hanjiang black pigs,followed by population ge-netics analysis and genomic characterization.The results show that Hanjiang black pigs are classified into four distinct families;Families 1,2,and 4 share similar lineage compositions,while Family 3 exhibits dis-tinct characteristics;Principal components analysis results align with Admixture outcomes;Homozygosity and inbreeding coefficients are consistent across the genome within each family of Hanjiang black pigs,with the number and length of Runs of Homozygosity(ROH)showing a linear correlation.Notably,fami-lies 1 and 2 display low inbreeding coefficients,whereas some individuals in family 4 and all of family 3 ex-hibit higher levels of inbreeding.The construction of a molecular pedigree and assessment of genomic char-acteristics based on SNP information offer valuable insights for the conservation and utilization of Hanjiang black pigs.关键词
