WebApr 17, 2009 · Mendelian variants have large effects on the phenotype so there is a clear correspondence between genotype at a locus and trait phenotype. For any trait there is a continuum of allelic effects from small to large: the large effects segregate as Mendelian variants, while the small effects segregate as quantitative genetic variation. WebFor example, Fried’s frailty phenotype, one of most widely used criteria in clinical practice (Fried et al., 2001), characterizes five typical phenotypes, that is, unintentional weight loss, low energy or self-reported exhaustion, low physical activity, slowness, and weakness. The severity of frailty is then categorized by simply summing the ...
