    Ecotype and polymorphism: an ecotype is a population of a species that is adapted to a particular environment; a polymorphism is a genetic variant within a species. So, a polymorphism is the genetic basis of the differences in phenotype in different ecotypes of a species.

    Cline and geographic isolates: a cline is a gradual change in a particular characteristic of a species from one end of its geographic range to the other; a geographic isolate is a ...
