Aim. The aim of the present paper was to evaluate the genotypic diversity of S. mutans in caries-free and caries-active preschool children in Brazil. Design. Twenty-eight preschool children were examined regarding caries experience by the dmft index. DNA from 280 isolates of S. mutans was extracted. S. mutans evaluated using to the PCR method, with primers for the glucosyltransferase gene. The ...

Principal components analysis on allele frequencies for 14 and 50 populations (from 1K Genomes and ALFRED databases) produced a factor accounting for over half of the variance, which indicates selection pressure on intelligence or genotypic IQ. Very high correlations between this factor and phenotypic IQ, educational achievement were observed (r>0.9 and r>0.8), also after partialling out GDP an...

to investigation of pathogenisity and genotype diversity of xanthomonas oryzae pv. oryzae (xoo) caused rice bacterial blight, several samples were collected from paddy field of rice in rasht-sangar, soumeh sara, rezvan shahr, daboudasht amol and rice-institute-research guilan during the summer of 2012, from plants that showed blight and yellowing in their leaves. bacterial isolates were identif...

The experiment was conducted to evaluate 24 coriander (Coriandrum sativum L.) genotypes during the rabi 2018- 19 season for yield and related traits assess correlation path analysis. Seed per plant positively significantly correlated with umbels plant, harvest index seed umbellate at both phenotypic as well genotypic level. characters namely index, branches days maturity showed positive direct ...

One hundred upland cotton germplasm accessions were evaluated for eight traits to evaluate the per se performance, genetic variability, heritability, advance as a cent of mean, correlation and path analysis. The estimation variability indicated that number monopodia plant had high GCV PCV. High heritability along with GAM was  found in height, internode length, plant, sympodia bolls seed y...

The experiment included 20 cowpea genotypes with three replications in a Randomized Block Design. study was carried out to estimate the genetic variability, advance, correlation coefficient analysis and yield contributing traits, direct indirect effects of component on through path analysis. variance revealed existence all hence data 17 traits which showed significant differences among entries ...

We describe additional phenotypic features in a boy and his mother. Both manifested the phenotypic/genotypic correlation of oto-palato-digital syndrome type II. The mother's radiographs showed wormian bones of the skull, and paranasal bossing, her feet showed bilateral fusion of the cuboid with the lateral cuneiform bone with subsequent development of metatarsus varus associated with dysplastic...
