The genomic comparison between autochthonous and cosmopolitan cows reveals structural variants involved in environmental adaptation.

ABSTRACT: Copy Number Variants (CNVs) are structural variants affecting genetic diversity and phenotypic variability of populations. Different authors underlined the relevance of CNV in relation to the adaptation to environmental conditions (e.g., altitude, harsh farming environment). Aosta cattle (Aosta Red Pied - ARP; Aosta Black Pied/Chestnut - ABC and Mixed Chestnut-Héren - ACH) farmed in the Aosta Valley, and the Oropa Red Pied (ORO), farmed in the Piedmont region, are autochthonous dual-purpose breeds well adapted to the natural Alpine environment. In contrast, the Holstein (HOL) breed is a specialized dairy breed raised in intensive farming systems, representing an artificial environment. The aim of this study is to use CNVs to characterize these breeds and explore the relationship between st
