Solution Preview

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 ...

Solution Summary

This solution is provided in about 310 words and discusses various ecological concepts. For the first part of the solution, the terms in question 1 are compared by explaining the meaning of each concept.
