| Abstract | Variation in the organisms comes as consequence of ontogenetic, environmental or genetic changes. Polymorphism is the discontinuous genetic variation associated with non-sexual processes. Polymorphism may or may not be conspicuous and results from changes in the DNA due mutations or recombination. Variation at the individual, population or species level allows to find inherited attributes (morphological or molecular) that show if the variants under study belong or not to the same organism, population or species. The presence of these shared attributes distinguishes the ontogenetic, population or historical individuality. This manuscript describes molecular markers used to sample variation within and among populations for ecological or systematic studies. Methods to obtain markers from proteins are reviewed first, followed by those from nucleic acids. Some of these molecular markers'are: immunological essays, isozyme electrophoresis, restriction fragment length polymorphisms, random amplified polymorphic DNAs, mini and microsatellites. single strand conformation polymorphism and DNA sequencing. Available molecular markers have helped solve diverse ecological and systematic problems, like: parentage, diversity, hybridization, geog'raphic variation, speciation and phylogeny, among others. These markers can be explored in any gene or gene product from any organism. |
