Despite the undisputed prominence of inheritance as the fundamental reuse mechanism in object-oriented programming languages, the variants – single inheritance, multiple inheritance, and mixin inheritance – all suffer from conceptual and practical problems. Traits overcome the problems arising with the different variants of inheritance. Traits are essentially groups of methods that serve as bui...

in order to investigation of morphological traits, yield and its components in three cultivars of grain sorghum (kimia, sepideh, payam) and two promising lines (m5, m2) under four density (240000, 205000, 170000 and 135000 plant/m2), experiment was conducted as factorial design based on randomized complete block design with three replications in birjand agricultural research station, during 200...

The development, function, and integration of morphological characteristics are all hypothesized to influence the utility of traits for phylogenetic reconstruction by affecting the way in which morphological characteristics evolve. We use a baboon model to test the hypotheses about phenotypic and quantitative genetic variation of traits in the cranium that bear on a phenotype's propensity to ev...
