Explanation:
Detailed explanation-1: -Height is a notoriously variable phenotype, which clearly ‘runs in the family’. Because of the latter, variation in height caught the interest of geneticists. Genome-wide association studies (GWASs) demonstrated that at least 180 loci for common variants were associated with adult height.
Detailed explanation-2: -Polygenic inheritance can be explained by additive effects of many loci: if each “capital” allele contributes one increment to the phenotype. With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
