BREEDING AND GENETICS Heterosis and DNA Fingerprinting in Chickens
Enhancement of performance in traits of economic importance by use of heterosis (hybrid vigor) is routine in poultry breeding. There is, however, no reliable method to predict the level of heterosis that will occur from the mating of individuals from two populations. DNA fingerprints (DFP) were used as a measure of genetic distance between mating pairs of chickens where each individual of a pai...
متن کاملPrediction of heterosis from DNA fingerprints in chickens.
To assess the value of DNA fingerprints for the prediction of heterosis in chickens, retrospective analyses of data from three crossbreeding experiments and DNA fingerprints (DEP) of parental strains were conducted using two minisatellite and one middle-repetitive DNA probes. DEP bands were assessed on pooled DNA samples of 10-15 individuals per parental genetic group. The number of DEP bands e...
متن کاملRandom amplified polymorphic DNA (RAPD) fingerprinting of Mycoplasma gallisepticum isolates from chickens
Ten field isolates of Mycoplasma gallisepticum (MG) from different geographical areas of Iran were analyzed by random amplification of polymorphic DNA (RAPD). RAPD analysis produced reproducible banding patterns on the basis of which various distinct amplification patterns could be detected. MG isolates compared with reference strains (S6 and Mg SS) and vaccine strain (ts-11) and demonstrated...
متن کاملAssessment of inbreeding by DNA fingerprinting: development of a calibration curve using defined strains of chickens.
By analyzing DNA fingerprints of chickens from seven well-defined genetic groups, a calibration curve was established relating the degree of inbreeding with the average band frequency, allelic frequency and band sharing. The probe used was bacteriophage M13 DNA and digestion of the genomic DNA was carried out with the MspI restriction enzyme. The analysis also provided an estimate of the averag...
