Understanding the genetic basis for these traits and its relationship with standard traits is necessary for this to be accomplished.
This is not an easy step, even with standard traits such as geographic location or morphological characters.
Though safflower possesses many of the standard traits that comprise the domestication syndrome (e.g., loss of seed dormancy, uniform flowering time, increased seed production, and increased seed oil quality and content), most cultivated safflower varieties have retained certain weed-like characteristics of their wild relatives (e.g., branching and leaf spines).
Standard trait correlations may be biased by species relatedness [39].
Importantly, from this same data-set, Feret diameter ratio, and Tooth area : blade area were considered among the most useful adaptive traits in multivariate approaches to temperature inference based on standard trait-climate correlations [12].
Using the latter, we demonstrate the likely genetic control of the reseda green-coloured shank phenotype, a standard trait for the breed.
Currently, Solanaceae breeders' ontology exists, and Rosaceae breeders also developed standard trait descriptors as part of RosBreed project, which are also stored in the cvterm table.
Volunteers were tested for standard personality traits, and Mischel compared the results with ratings of how well the volunteers performed in the field.
Confirmatory factor analyses were applied to a unidimensional model, to a standard correlate traits model, to second-order representations of a common latent structure, and to a bifactor model.
Alternatively, if filmmakers were to create a superhero -- complete with the standard superhero traits such as strength, ability to fly, etc. -- they would be at a complete disadvantage, and even the slightest failure to educate the audience on the characters could result in failure.
