DNA polymorphisms in human population studies: a review.

The use of restriction endonucleases and DNA probes to expand the range of informative polymorphisms should be of immense value in the study of human populations. To date, this approach has been only minimally used, but results are available for markers in the major histocompatibility complex and the globin gene clusters. In addition, isolated studies using other probes have been published. The ease of the techniques involved, the rate at which new DNA polymorphisms are being found and the range of information provided should ensure that use of this approach expands rapidly.
