A collection of particular persons or items, formed into one body; as a corporation aggregate, which is one formed of a number of natural persons; the union of individual charges make an aggregate charge.
3. Pleiotropy (or pliotropy) is the phenomenon in which a single gene conditions several different phenotypical traits. Some phenotypical traits may be sensitive to the pleiotropic effects (for example, inhibition) of other genes, even when conditioned by a pair of alleles in simple dominance.A mixture of pleiotropy and gene interaction is characteristic of these cases.1  Non-Mendelian Inheritance-Image Diversity: pleiotropy.ome phenotypical traits may be sensitive to the pleiotropic effects (for example, inhibition) of other genes, even when conditioned by a pair of alleles in simple dominance.

Ad. Pleiotropy can, at times, cause harm to an organism. This happens when a defect in a single gene causes negative effects relating to several different traits of an organism. One example of this is the disease PKU, or phenylketonuria, which occurs in humans.d. Pleiotropy can, at times, cause harm to an organism.
