Multilocus and single locus minisatellite analysis in population biological studies.

In this review we describe the situations in which minisatellite analysis is of value to studies of population and evolutionary biology. Evolutionary and population biologists need to be able to quantify genetic relationships among individual organisms at many different levels, from close familial relationships to evolutionarily distant phylogenetic ones. The use of minisatellite markers is put into this context and compared with the other molecular biological techniques. Examples of the use of multilocus minisatellite analysis in population biology are described. The limitations of multilocus fingerprinting are presented, together with the potential advantages of locus-specific probes. The use of locus-specific probes in population biology is now often feasible due to the recent development of a cloning system which allows their efficient isolation. The availability of locus-specific probes should significantly expand the role of minisatellite markers in population biology.
