the aim of this study was to access the genetic differentiation of paraschistura sp. in kheirabad and brim rivers (zohreh river system, persian gulf basin), iran. for this purpose, 60 samples including 30 male and 30 female samples from each river were collected. a total of six microsatellite loci (bbar4, bbar7, ic228, ic230, ic434 and ic720) were used and all of them showed high polymorphism (...

to clarify the genetic relationships among the lidia breed lineages and two main portuguese lidia bovine populations, casta portuguesa and brava dos açores, 24 autosomal microsatellites were analyzed in 120 samples. brava dos açores showed the highest observed and expected heterozygosity (0.73 and 0.70, respectively) while casta portuguesa showed the lowest observed and expected heterozygosity ...

Habitat gap size has been negatively linked to movement probability in several species occupying fragmented landscapes. How these effects on movement behaviour in turn affect the genetic structure of fragmented populations at local scales is less well known. We tested, and confirmed, the hypothesis that genetic differentiation among adjacent populations of Florida scrub jays--an endangered bird...

Restriction fragment length polymorphism (RFLP) analysis and partial-genome DNA sequencing are commonly used to infer genetic relationships among pathogens. This study compares the application of both techniques to the analysis of 16 pseudorabies virus isolates collected during a 1989 outbreak. Genetic distances derived from RFLP and DNA sequence data were not significantly correlated with geog...

This paper investigates an improved genetic algorithm on multiple automated guided vehicle (multi-AGV) path planning. The innovations embody in two aspects. First, three-exchange crossover heuristic operators are used to produce more optimal offsprings for getting more information than with the traditional two-exchange crossover heuristic operators in the improved genetic algorithm. Second, dou...

Linear functions of Nei's genetic-distance statistic are calculated frequently in the literature of population genetics. Variance estimates for these linear functions are either not presented or incorrectly calculated. Part of the problem stems from the common assumption that distance statistics are independent random variables. This assumption is not generally correct. We describe methods for ...
