Zur Evolution von Short Tandem Repeats
The stepwise mutation model (SMM) is a simple, widely used model to describe the evolutionary behaviour of microsatellites. We apply a Markov chain description of the SMM and derive the marginal and joint properties of this process. In addition to the standard SMM, we also consider the normalised allele process. In contrast to the standard process, the normalised process converges to a stationa...
متن کاملMutation of human short tandem repeats.
A total of 20,000 parent-offspring transfers of alleles were examined through the genotyping within 40 CEPH reference families of 28 short tandem repeat polymorphisms (STRPs) located on chromosome 19. Forty-seven initial mutation events were detected in the STRPs using DNA from transformed lymphoblastoid cell lines, but less than half (39%) could be verified using DNA from untransformed cells. ...
متن کاملForensic Applications of Y-Short Tandem Repeats.
Y-short tandem repeats (STRs) are located in the nonrecombining part of the Y-chromosome. Its genetic characteristics are helpful to paternity testing. The male lineage can be pursued over several generations. Since an overwhelming majority of rape or sexual assault cases involve male suspects, these markers proved to be very useful with mixed stains. Routine casework performed in our laborator...
متن کاملShort tandem repeats and genetic variation.
Single nucleotide polymorphisms (SNPs) are widely distributed in the human genome and although most SNPs are the result of independent point-mutations, there are exceptions. When studying distances between SNPs, a periodic pattern in the distance between pairs of identical SNPs has been found to be heavily correlated with periodicity in short tandem repeats (STRs). STRs are short DNA segments, ...
متن کاملZygosity determination in newborn twins using DNA variants.
A prerequisite for the optimal use of the twin method in human genetics is an accurate determination of the zygosity at birth. This diagnosis is sometimes hampered by the lack of available specific markers. We report here the use of DNA variants (restriction fragment length polymorphisms) as genetic markers for zygosity determination. We have analysed the placental DNA of 22 twin pairs with kno...
