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.

The physical appearance of an organism with respect to a trait, i.e. yellow (Y) or green (y) seeds in garden peas. The dominant trait is normally represented with a capital letter, and the recessive trait with the same lower case letter. pleiotropic. A single gene determines more than one phenotype for an organism.
