• The application of such a model occurred later in tree breeding, and is much less common than in animal breeding. (McRae et al., 2003)
• Among the studied species are several less common species which are of interest to foresters to increase biodiversity and ecosystem resilience, but for which relatively little information exists in the literature. (Walentowski et al., 2017)
• In a GWA study, the ability to detect an association at a particular SNP decreases with the frequency of the less common variant at that SNP. (Nordborg, Weigel, 2008)
