<P> It has also been studied in alfalfa, shrews, Brazilian rodents, and an enormous variety of other animals and plants . In one instance it has been found in a human . </P> <P> Another process resulting in differing chromosomal counts is polyploidy . This results in cells which contain multiple copies of complete chromosome sets . </P> <P> Possessing chromosomes of varying shapes is generally the result of a chromosomal translocation or chromosomal inversion . </P> <P> In a translocation, genetic material is transferred from one chromosome to another, either symmetrically or asymmetrically (a Robertsonian translocation). </P>

What kinds of changes to chromosomes would cause a polymorphism
