In total, 41 different microsatellite variants have been typed in one or more of four different sets of recombinant inbred (RI) mouse strains. Microsatellite variants were selected that were located in chromosomal regions previously lacking markers. These markers extend the regions swept in these RI

β¦ Synopsis
Mouse sequence information from the EMBL and GenBank databases, published sequences and genomic clones have been analyzed for simple repetitive elements or microsatellites. Each microsatellite has been amplified by the polymerase chain reaction (PCR) as a single locus marker. PCR primers were designed from unique sequence flanking each repeat. Size variation of PCR products less than 750 base pairs (bp) between mouse strains has been determined using ethidium bromide-stained acrylamide or agarose gels. A further 74 newly characterized microsatellites are presented in this paper, bringing to 185 the total we have analyzed. Of these, 157/185 (85%) have more than one allele, 143/178 (80%) vary in length between C57BL/6J and Mus spretus, and 82/168 (49%) vary between DBA/2J and C57BL/6J. Microsatellites provide informative single locus probes for linkage analysis in the construction of a genetic map of the mouse genome.

Eighty sequences from the mouse genome database containing microsatellites (simple sequence repeats) have been analyzed for size variation among ten different inbred strains of mice; 62/80 (77.5%) showed polymorphism of at least three alleles. We have been able to detect all the polymorphisms by aga
Previous research has mapped an ovulation rate quantitative trait locus (QTL) to bovine chromosome 19. In an effort to enhance comparative mapping information and develop additional markers for refined QTL mapping, microsatellite markers were developed in a targeted approach. A bovine bacterial arti
Single nucleotide polymorphisms (SNPs) are the most prevalent form of DNA sequence variation in humans. At the end of 2008, public databases contained more than 12 million entries of genetic variants in humans, the vast majority of which are SNPs [1]. While the incidence of SNPs in the human genome
