Next, the strength of selection is determined by the proportion of individuals selected each generation to create the next generation.
"As the winters have become shorter, the strength of selection has been reduced a little bit," Dr. Coulson said.
More generally, the strength of selection differed considerably between the major families of microbial sensors.
It is important to determine the strength of selection at transmission because it can increase the proportion of respiratory droplet transmission enabling substitutions.
The distance between the 2 colors in color space determined the strength of selection.
In particular the strength of selection acting on a region may be an important quantity to examine (e.g. [10]).
Hence, the strength of selection identified in our population could potentially work also in the smallest of populations.
It is therefore likely that a color sensitive area determines the strength of selection between the 2 surfaces.
In general, the strength of selection on robustness to some form of perturbation is limited by the fitness load that the perturbation can create [16].
Hence the strength of selection S is proportional to the expected reproduction by males at ages older than J, which equals Σn>JGnMlnMλ−n.
We demonstrate that purifying selection against mildly deleterious alleles is the dominant force governing cis-regulatory evolution in S. cerevisiae and estimate the strength of selection.
