Because higher heritability traits are more responsive to selection than low heritability traits, these high heritabilities indicate that selection for the more predominant provitamin A compounds should be effective.
Since ROS levels are important to cell growth, the possibility exists that ROS modulation has been responsive to selection pressure.
However, there are about 20 races of maize in the highlands of Mexico (Wellhausen et al. 1952; Sanchez et al. 2000) and we do not know if all these races would have similar problems responding to warmer conditions, or if some could be more plastic or responsive to selection.
Population size has been invoked to be one key variable for the possibility of evolutionary rescue (ER) of populations under changing environments, either by determining the amount of quantitative genetic variation responsive to selection, or indirectly via inbreeding effects (Willi et al. 2006).
Analyses of haplotype and nucleotide diversity based on 50 rice accessions which included improved cultivars, landraces, and wild species were conducted to reveal if the gene has been responsive to artificial selection and the associated geographic distribution of its alleles.
Additionally, insertion of a TE into a single Hsp70 promoter creates allelic variation that is apparently responsive to positive selection [12], [15].
The anterior part of the l-VLPFC (roughly coextensive with the left IFG-orbitalis) is thought to be involved in controlled lexical retrieval, whereas the left mid-VLPFC (∼IFG-triangularis) is thought to be responsive to postretrieval selection demands, or alternatively demands on cognitive control (Kan and Thompson-Schill 2004; Badre and Wagner 2007; Schnur et al. 2009).
The paper also gives measured on-street public transport benefits which have arisen from using a simple rule-based (traffic-responsive) signal plan selection system, compared with a time-tabled signal plan selection system.
The three most frequently occurring sequences displayed a high level of similarity to sequences identified in the previous DIS-responsive aptamer beacon selection[ 12] (Table S1).
As vendors start shipping smaller quantities and being less responsive, the inventory and selection at Sears stores is going to get even worse than it already is.
However, we interpret our set of predicted GR targets as strongly enriched for primary responsive genes, given the selection criterion, the relatively short time after treatment, and the fact that the mRNAs were always up regulated, as would be expected from the compound HRE mediated action.
