Question

How are genetic polymorphisms used to distinguish populations?

Answer 1

Polymorphism is a discontinuous genetic variation that results from the occurrence of several different forms or types of individuals among the members of a single species. A discontinuous genetic variation is responsible to divide the individuals of a population into two or more sharply distinct forms. The example: separation of many higher organisms into male and female sexes. A polymorphism that can persist over many generations is normally maintained because there is no overall advantage or disadvantage for natural selection. Some polymorphisms have no visible manifestations and require biochemical techniques to determine the differences that occur between the chromosomes, proteins, or DNA of different forms.
