Unformatted text preview: the same rate in the gel. DNA variation. Measure the genetic material directly; sequencing is the most precise but the most laborious; restriction enzyme analysis faster but has less information. These techniques have revealed that there is even more genetic variation that what was revealed by protein electrophoresis. Hence the debate between the Classical and Balance schools of genetic variation has evolved into a debate about the forces maintaining genetic variation: the Neutralist-Selectionist controversy (or debate). Some loci are neutral; others under selection (more in lecture on Molecular Evolution). The debate is not over. How is variation apportioned within and among populations? Hierarchy in patterns of variation: are populations either melanistic or normal; or do populations contain some of both; if so what are the frequencies in different populations? Is the variation within or among populations ? Spatial Patterns of Variation...
