Italian Local Chicken Breeds: A Comparative Analysis of Biodiversity on a Global Scale

The raw dataset was then integrated with genotypic data from various chicken breeds worldwide to explore the genetic relationships between Italian and global biodiversity. Genotypic information for 3,047 animals representing 167 breeds was obtained from Malomane et al [8], establishing a global dataset. All individuals retrieved from Malomane et al [8] were genotyped with the Affymetrix Axiom 600K Chicken Genotyping Array. After merge, the final dataset consisted of 3,720 animals, 467,723 common SNPs, and 192 breeds, divided according to geographical origin
