Document Summary

Microevolution: is a heritable change in the genetic makeup of a population. Population: includes all individuals of a single species that live together in the same place and time. Phenotypic variation: differences in appearance or function that if based on heritable information are passed from generation to generation. 16. 1a evolutionary biologists describe and quantify phenotypic variation. Microevolutionary studies often begin by assessing phenotypic variation within populations. Most characters exhibit quantitative variation individuals differ in small, incremental ways. Other characters exhibit qualitative variation they exist in two or more discrete states, and intermediate forms are often absent. Polymorphism: existence of discrete variants of a character. 16. 1b phenotypic variation can have genetic and environmental causes. Phenotypic variation within populations may be caused by genetic differences between individuals, by differences in the environmental factors, and a combination of both. Therefore genetic and phenotypic variations may not be perfectly correlated.
