Interpretive Summary: An editorial review was conducted on a special issue on genetic diversity and selection signatures in composite breeds. The special issue was published in Frontiers in Genetics journal. This Research Topic was designed to compile original studies investigating the genetic diversity of composite breeds and potential footprints of selection in their genome and demonstrate the usefulness of genomic information to understand population structure, breed formation, and better understand the genetic background of local genetic resources. This Research Topic included 15 papers.

Technical Abstract: Since domestication of livestock species, numerous breeds have been developed through natural and artificial selection for specific traits. In addition to organized crossbreeding schemes (e.g., in poultry and swine breeding industries), composite breeds have also been created through crossing breeds with complementary characteristics for multiple generations. As composite breeds also undergo intensive selection, signatures of selection could be formed in their genome, which could provide important background knowledge on their selection history and genomic structure. However, most previous studies focused on pure breeds. Therefore, this Research Topic was designed to compile original studies investigating the genetic diversity of composite breeds and potential footprints of selection in their genome and demonstrate the usefulness of genomic information to understand population structure, breed formation, and better understand the genetic background of local genetic resources.
