Shell says he bases stock selections on how strong the company is positioned on the Internet, and doesn't care whether it originated in cyberspace or in the brick-and-mortar world.
Thus, for a particular gene, mutations in the promoter region may be negatively selected or may be an opportunity for positive selection depending on how changes in the concentration of its coded protein affect the functioning of the cell.
She had a fairly abstract approach to her selection, focusing on how things might work in groups.
We made a selection based on how inspired we felt by a dish, by how difficult it would be to prepare, and by the aesthetics and name of it.
Sustainability of the response to selection depends on how the additive variance changes through time.
Further research on the effect of selection and on how to handle appropriately the issue with allele frequencies is needed.
Although the gradients are derivatives of the expected average number of adult offspring produced (w m m and w m f ), the direction of selection depends on how the phenotype affects the average number of juvenile offspring produced as well as reproductive variance.
Together they will be able to analyze phenotypes at a chemical level, and make breeding selections based on quantified amounts of cannabinoids as opposed to making breeding selections based on how something looks, or how high you get when you smoke it.
Comparing the two, therefore, provides a way to determine how selection on one trait is influenced by selection on other traits (Lande and Arnold 1983).
We calculated the model selection probabilities based on how many times a permissible model was selected in the bootstrap samples.
