A major locus that is detected through its effect on one phenotype (a primary trait) may also affect other quantitative phenotypes or qualitative disease endpoints (secondary traits). The pattern of effects of the major locus on a set of primary and secondary traits suggests candidate defects for the mutant allele. The effects are directly estimable when "measured genotypes" or a tightly linked...

The impact of among-environment heteroscedasticity and genetic autocorrelation on the analysis of phenotypic plasticity is examined. Among-environment heteroscedasticity occurs when genotypic variances differ among environments. Genetic autocorrelation arises whenever the responses of a genotype to different environments are more or less similar than expected for observations randomly associate...

to investigate the genotypic and phenotypic relationship between characteristics affecting tomato fruit weights, eleven tomato lines were compared in a rcb design with three replications. the anova showed that the difference among lines was significant for all characteristics. there was a significant phenotypic and genotypic correlations between fruit weight and most of the characteristics. the...

Genotypic correlations and regressions can be estimated from multiallelic data sets either by weighting the allelic effects additively or by specifically weighting the genotypic interactions. Both methods can be extended to multiple loci, but they do not fully take into account the joint segregation patterns at the loci. These genotypic statistics have a great importance in sociobiological cont...

Pd and Co nanoparticles were deposited on cellulose for use as a heterogeneous catalyst in the bimetallic catalytic reduction reaction. The catalyst was characterized with Energy Dispersive X-Ray Spectroscopy, X-Ray Diffraction pattern, Thermal Gravimetric Analysis, Flame Atomic Absorption Spectroscopy, and Transmission Electron Microscopy, and applied in the reduction reaction of nitroarom...

The objectives of this study were to assess the genotype (G) by environment (E) interaction of grain yield of durum wheat(Triticum durum Desf.) based on parametric models, additive main effects and multiplicative interaction (AMMI) and joint linear regression models; and compare the relative efficiency of the two models in explaining the GE effects. Twenty-three genotypes were evaluated across ...

Blastomycosis is a serious and potentially fatal infection caused by the thermally dimorphic fungus Blastomyces dermatitidis. Polymerase chain reaction (PCR) assays targeting the BAD-1 virulence gene promoter have been developed to aid in the detection of the pathogen in clinical and environmental samples. However, little is known regarding the genetic diversity of B. dermatitidis and how this ...

BACKGROUND The clinical importance of low-level mupirocin resistance and genotypic chlorhexidine resistance remains unclear. We aimed to determine whether resistance to these agents increases the risk of persistent methicillin-resistant Staphylococcus aureus (MRSA) carriage after their use for topical decolonization therapy. METHODS A nested case-control study was conducted of MRSA carriers w...
