Strategies for CNV discovery in animal and plant species and their use in breeding
Copy Number Variants (CNVs) are a novel type of polymorphism involving large regions, often corresponding to duplications or deletions of chromosomal fragments, including sometimes expressed genes. These CNVs have been discovered recently and are under strong investigations because of their potential functional effect. Since 2003-2004, CNVs have been documented in an increasing number of species. However, despite their potential impact, CNV surveys have been done only for a limited number of animal breeds and plant cultivars.
