The relationship between mitochondrial DNA haplotype and its copy number on body weight and morphological traits of Wuliangshan black-bone chickens.

ABSTRACT: Mitochondria play a pivotal role as carriers of genetic information through their circular DNA molecules. The rapid evolution of the D-loop region in mitochondria makes it an ideal molecular marker for exploring genetic differentiation among individuals within species and populations with close kinship. However, the influence of mtDNA D-loop region haplotypes and mtDNA copy numbers on phenotypic traits, particularly production traits in chickens, remains poorly understood. In this comprehensive study, we conducted D-loop region amplification and sequencing in the blood mitochondria of 232 female Wuliangshan black-bone chickens. Our investigation identified a total of 38 haplotypes, with a focus on 10 haplotypes that included more than five individuals. We meticulously analyzed the correlat
