An example of a botanical genetic polymorphism is heterostyly, in which flowers occur in different forms with different arrangements of the pistils and the stamens. The system is called heteromorphic self-incompatibility, and the general 'strategy' of stamens separated from pistils is known as herkogamy.enetic polymorphism is actively and steadily maintained in populations by natural selection, in contrast to transient polymorphisms where a form is progressively replaced by another. By definition, genetic polymorphism relates to a balance or equilibrium between morphs.
Polymorphism is a change in DNA sequence, which is common in a population. In other words, there needs to be more than one phenotype for a particular character in a population for it to be called polymorphism.y HAW. Mutation vs Polymorphism. In eukaryotes, DNA is found in chromosomes in the nucleus. Chromosomes are made of a single molecule of DNA and histone proteins. Chromosomes are linear, and DNA in them is double stranded. There are many chromosomes in a single nucleus.
