Document Summary
Microevolution a heritable change in the genetic makeup of population. Population all the individuals of a single species that live together in the same place and time. Phenotypic variation differences in appearance or function that are passed from generation to generation. Qualitative variation exist in two or more discrete states, and intermediate forms are often absent. Polymorphism the existence of discrete variants of a character (poly=many , morphos=form) Artificial selection a population expressing quantitative traits that have a genetic basis can be selectively bred to change the average value of the trait. Null models predict what they would see of a particular factor had no effect. Handy weinberg principle specifies the conditions under which a population of diploid organisms achieve genetic which a population of diploid organisms achieve genetic equilibrium, the point at w/c neither allele frequencies change in succeeding generations. >according to this model, genetic equilibrium is possible only if all of the following conditions are met:
