Population Structure and Genetic Diversity Analysis of Lueyang and Zhenping Black-Bone Chicken
摘要
Abstract
Lueyang black-bone chicken(LBC)and Zhenping black-bone chicken(ZBC)are unique black-bone chicken populations native to Shaanxi Province.Due to their rich nutrition and popularity a-mong consumers,they have substantial commercial value.However,few studies to date have comprehen-sively elucidated the genomic characteristics of these two populations.In this study,samples were collected from 20 Lueyang Black-Bone Chicken(LBCs)and 20 Zhenping Black-Bone Chicken(ZBCs)for whole ge-nome re-sequencing.Additionally,SNP datasets were compiled by incorporating publicly available data from 110 chickens.Population structure analysis revealed that the clustering patterns of local chicken pop-ulations are related to their geographical location.LBC and ZBC exhibited the closest genetic distance and indicated a mixture of genetic components of Chinese northern and southern domestic chickens.Genetic di-versity analysis showed that LBC and ZBC had relatively high observed heterozygosity,faster linkage dise-quilibrium decay,and lower inbreeding coefficients,indicating that they have rich genomic genetic diversi-ty.This study deepens the understanding of the population structure of Shaanxi local black chicken breeds and has significant implications for the conservation of germplasm resources in LBC and ZBC.关键词
