The applicability of bovine autosomal microsatellite markers for population genetic studies on African buffalo was investigated. A total of 168 microsatellite markers were tested for PCR amplification on a test panel of seven African buffalo. Amplification was observed for 139 markers (83%), and 101 markers were studied further with 91 (90%) being polymorphic. The mean number of alleles per mar...

Highly informative genetic markers are essential for efficient management of cattle populations, as well as for food safety. After a decade of domination by microsatellite markers, a new type of genetic marker, single nucleotide polymorphism (SNP), has recently appeared on the scene. In the present study, the exclusion power of both kinds of markers with regards to individual identification and...

Microsatellite DNAs (or SSRs) are important genomic components involved in many important biological functions. SSRs have been extensively exploited as molecular markers for diverse applications including genetic diversity, linkage/association mapping of gene/QTL, marker-assisted selection, variety identification and evolution analysis. However, a comprehensive database or web service for study...

Pedigree reconstruction using molecular markers enables efficient management of inbreeding in open-pollinated breeding strategies, replacing expensive and time-consuming controlled pollination. This is particularly useful in preferentially outcrossed, insect pollinated Eucalypts known to suffer considerable inbreeding depression from related matings. A single nucleotide polymorphism (SNP) marke...

AIM To evaluate the population substructure of purebred dogs and cats in order to estimate the true significance of a microsatellite-based DNA match for use as evidence in legal proceedings. The high frequency of animal hair as a forensic evidence submission necessitates the development of mitochondrial analysis tools as well. METHODS Random samples from a large convenience collection of vete...

A panel of polymorphic microsatellite markers have been developed in coast redwood (Sequoia sempervirens). Two loci in particular (Seq18D7-3 and Seq21E5) demonstrate the potential of microsatellite genotyping in the assessment of genetic diversity and inheritance in redwoods. The highly polymorphic Seq18D7-3 marker provided evidence for the planting of non-local redwood seedlings in a restored ...

Genetic relationships among 20 elite wheat genotypes were studied using microsatellite markers and pedigree analysis. A total of 93 polymorphic bands were obtained with 25 microsatellite primer pairs. Coefficient of parentage (COP) values were calculated using parentage information at the expansion level of 5. The pedigree-based similarity (mean 0.115, range 0.00-0.53) was lower than the simila...

Variation in queen number alters the genetic structure of social insect colonies, which in turn affects patterns of kin-selected conflict and cooperation. Theory suggests that shifts from single- to multiple-queen colonies are often associated with other changes in the breeding system, such as higher queen turnover, more local mating, and restricted dispersal. These changes may restrict gene fl...
