1. Minisatellites, originally developed for forensic DNA fingerprinting and profiling, have also provided extremely informative systems for analysing processes of tandem repeat DNA turnover in the human genome. 2. Minisatellite instability involves distinct mutation processes in somatic and germline cells. In sperm, tandem repeat instability most likely arises at meiosis as a by-product of high...

We report the exclusion of a locus for autosomal dominant retinitis pigmentosa proximal to the rhesus locus in a single large pedigree. In addition, a previously unreported linkage is described between two chromosome 1 markers, which confirms that a highly variable minisatellite locus is placed internally on chromosome 1.

We have studied the allelic diversity and de novo mutations at the hypervariable minisatellite locus D7S22. A four-state minisatellite variant repeat unit mapping by PCR (MVR-PCR) method was developed for this purpose, and a substitution polymorphism close to the repeat array was used to design allele-specific flanking primers to study individual haplotypes in genomic DNA. A total of 150 allele...

Analyses of genetic diversity within populations could be of great benefit to plant genetic resources conservation . In order to identify genetic markers that are variable within populations, the genome of Phaseolus vulgaris was screened with several DNA sequences in order to identify hypervariable sequences . Polymorphisms were observed between Middle American and Andean cultivars using the pr...

We genotyped 297 Scottish C. parvum samples using micro- and minisatellites. Treated as a single population, the population structure was epidemic. When regional populations were analysed, there was evidence of sub-population structure variations. This was dependent upon excluding sub-groups exhibiting significant genetic distance from the main population, implying genetic sub-structuring. We t...
