Extreme phenotypes are favored
WebDirectional selection takes place when an exaggerated phenotype is favored and the distribution curve alters in that direction. Such a shift can happen when a population is adjusting to a changing environment. Disruptive selection occurs when two or more extreme phenotypes are favored over any other ordinary phenotype. WebWhen two phenotypic extremes of a trait are being selectively favored, then a natural population is under going _____ selection Disruptive When the intermediate phenotype of a trait is being selected for and the extreme phenotypes are being selected against, the population is probably undergoing
