Half tetrad analysis in alfalfa using multiple restriction fragment length polymorphism markers.
A maximum likelihood approach of half tetrad analysis (HTA) based on multiple restriction fragment length polymorphism (RFLP) markers was developed. This procedure estimates the relative frequencies of 2n gametes produced by mechanisms genetically equivalent to first division restitution (FDR) or second division restitution and simultaneously locates the centromere within a linkage group of RFL...
متن کاملRestriction Fragment Length Polymorphism (RFLP)
Restriction Fragment Length Polymorphism (RFLP) is a technique in which organisms may be differentiated by analysis of patterns derived from cleavage of their DNA. If two organisms differ in the distance between sites of cleavage of a particular restriction endonuclease, the length of the fragments produced will differ when the DNA is digested with a restriction enzyme. The similarity of the pa...
متن کاملApplications of restriction fragment length polymorphism.
The availability of a variety of restriction endonuclease enzymes that cleave deoxyribonucleic acid (DNA) at specific sites has made it possible to identify the presence of polymorphic regions in the isolated fragments. Such restriction fragment length polymorphism (RFLP) results owing to a variation in the number of tandem repeats (VNTR) of a short DNA segment. These VNTR sequences can uniquel...
متن کاملRestriction fragment length polymorphism (RFLP) analysis and tuberculosis epidemiology.
In order to study polymorphisms of the DNA insertion sequence 6110 (IS6110) in Mycobacterium tuberculosis strains isolated from Colombian patients, together with resistance to antituberculous medications in the Department of Quindío, Colombia, a prospective study was conducted using a consecutive sample of 59 patients with symptomatic pulmonary tuberculosis whose cases had been confirmed by bac...
متن کاملRestriction fragment length polymorphism analysis of Rhizobium galegae strains.
Total DNA of various Rhizobium galegae strains representing different geographical origins, and taxonomic divergence was digested with three restriction enzymes separately, Southern blotted, and hybridized with six heterologous probes. The sequence divergences for different pairwise comparisons were calculated from proportions of conserved hybridizing fragments. The unweighted pair group method...
