WebPhenotypic variation is essential for evolution . Without a discernable difference among individuals in a population there are no genetic selection pressures acting to alter the variety and types of alleles (forms of genes) present in a population. Accordingly, genetic mutations that do not result in phenotypic change are essentially masked ... Webvariation: ( var'ē-ā'shŭn ), 1.
