Men love to wonder, and that is the seed of science.
One of the first goals is to generate a high resolution linkage map of the genome. The most commonly used class of STRP has been the CA dinucleotide repeat. In addition to this, there is some evidence that this class of repeat is not evenly distributed. In order to generate maps consisting of markers that are robust to genotyping, are readily usable by a variety of groups with different levels of technological expertise, and whose distribution might complement that of dinucleotide repeat sequences, are being constructed maps with tri- and tetranucleotide repeat markers.
