PCAs and population STRUCTURE analyses of three cattle breeds (VRP, IBS and HOL) based on CNVs.

Twelve subpopulation clusters inferred by STRUCTURE are represented by different colors (K2-K12). A) Analyses run considering presence or absence of a CNV in a CNVR as described as Analysis 1 in the Materials and Methods section. B) Analyses run considering the CNV total copy number in a CNVR as described as Analysis 2 in the Materials and Methods section.
