Abstract excerpt

To characterize the genetic diversity and evolutionary patterns of four Weining chicken strains from Guizhou Province, China, we generated genome-wide single nucleotide polymorphisms (SNPs) using dd-RAD sequencing. We found that Weining chicken exhibited moderate genetic diversity, with observed heterozygosity (Ho = 0.267) lower than expected heterozygosity (He = 0.312) and a positive inbreeding coefficient (FIS...
