Usually, genetic selection is carried out based on several traits, which can be genetically correlated. When a kinship matrix reflects allelic correlations across genomewide snps and individuals are unrelated, then the proportion of phenotypic variance it explains is an estimate of the snp heritability of the phenotype the total.
