Description
Wenpeng Li and four co-authors wrote this 2024 study on the genetics of a prized Chinese chicken, the Wuliangshan black-bone breed. Beyond the main genome, cells carry small rings of DNA inside mitochondria, the cell's power plants. A fast-changing stretch of that DNA sorts chickens into family lines called haplotypes, and the team asked whether those lines track body traits.
They read the stretch in 232 hens and found thirty-eight haplotypes, focusing on ten common ones. Birds from different lines differed in weight and in several body measures, from chest depth to leg length. For some lines, more copies of the mitochondrial DNA went with bigger traits; for others the pattern was uneven. Family-tree analysis also traced the breed's roots to two subspecies of red jungle fowl. The data aid efforts to protect and certify this breed.
