Polymorphism is the capacity of multiple objects to respond to the same message in a particular manner. Definition of polymorphism. Polymorphism is an item’s volume to accept multiple kinds. WebStructural variation. This is a large (greater than 50 base pairs) rearrangement of part of the genome, and can be a deletion, duplication, insertion, inversion, translocation or often a combination of these. A copy number variation (CNV) is a duplication or deletion that changes the number of copies of a particular DNA segment within the genome.
