Maintenance of Genetic Variation in Plant Populations

  • Chapter
Evolutionary Biology

Abstract

The presence of genetic variation within populations is a prerequisite for adaptation and evolutionary change. All genetic variation is ultimately generated through mutation. If a mutation has no effect on the fitness of individuals, the frequency of the mutant in the population will be determined by stochastic factors [a subject thoroughly dealt with by Wright (1969)]. On the other hand, where significant amounts of genetic variation affecting fitness are found in natural populations, a selective explanation for the maintenance of this variation must be sought.
