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.

Allotropy or allotropism (from Greek á¼Î»Î»Î¿Ï (allos) , meaning other, and ÏÏÏÏÎ¿Ï (tropos) , meaning manner, form) is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of these elements.llotropes are different structural forms of the same element and can exhibit quite different physical properties and chemical behaviours. The change between allotropic forms is triggered by the same forces that affect other structures, i.e. pressure, light, and temperature.
