Restriction mapping is used to estimate nucleotide sequence polymorphism when the regions to be studied are too long or too numerous to be sequenced. Restriction mapping is less costly than DNA sequencing, but it does not allow direct measurement of underlying nucleotide polymorphism. It is therefore useful to be able to estimate underlying nucleotide polymorphism from observations of polymorph...

The aims of the present study were to propose apolymerase chain reaction-restriction fragment length polymorphismPCR-RFLP genotyping method for the AY_376689:c.773C>T single nucleotide polymorphism SNP of the equine PRKAG3 gene, related to muscle performance, as well as to characterize this SNP and a second polymorphism, AAWR_02017454:g.121684T>C of the SPATA1 gene, related to male fertility, i...

We investigated nucleotide polymorphism in the Adh1 locus of pearl millet (Pennisetum glaucum) (Poaceae) by determining the DNA sequence of 20 alleles from 10 individuals. The individuals were sampled from throughout pearl millet's indigenous range and represent both wild and cultivated accessions. Our results indicated that there is little nucleotide polymorphism in the Adh1 locus. Estimates o...

Microarrays are widely used to evaluate gene expression at the genome scale. However, all too often the importance of data analysis at the level of the individual probe is overlooked. This is a particular problem when trying to detect differences in gene expression levels among genetically unique animals, across inbred animal strains, or among genetically modified animals. Of particular concern...

background: trichomonas vaginalis is the agent of urogenital tract infection that causes human trichomoniasis with some serious health complications. more understanding about genetic features of the parasite can be helpful in the study of the pathogenesis, drug susceptibility and epidemiology of the infection. for this end,we conducted analysis of the actin gene of t. vaginalis by applying the ...

mastitis is one of the most serious and costly diseases affecting dairy cattle production. in the present study, effects of a lactoferrin gene polymorphism (intron 6) on milk somatic cell count (scc) and subclinical mastitis was investigated in 121 holstein dairy cattle. two alleles of a and b and two genotypes of aa and ab were found in an ecori recognized single nucleotide polymorphism in int...

Proper management and genetic monitoring of the modern European bison (Bison bonasus) population is one most important responsibilities for this species’ conservation. Up-to-date, complex analysis performed using a consistent molecular method needed as tool to further validate maintain diversity species. The identification line when pedigree data are missing, well parentage individuals, crucial...

Single-nucleotide polymorphism (SNP) mapping is the easiest and most reliable way to map genes in Caenorhabditis elegans. SNPs are extremely dense and usually have no associated phenotype, making them ideal markers for mapping. SNP mapping has three steps. First, recombinant mutant animals are generated over a polymorphic strain (usually CB4856) using standard genetic techniques. Second, the ge...
