Lower fitness costs, higher discrepancy in generation times (i.e., higher g) and higher mutation rates all act to reduce the realised strength of interaction.
Understanding how the causes of cancer, such as aging or smoking, affect tissue microenvironments to control the impact of mutations on somatic cell fitness can help reconcile the discrepancy between marked mutation accumulation starting early in life and the somatic evolution that leads to cancer at advanced ages or following carcinogenic insults.
One critical function of these is to ensure that cells do not become committed to a biological process without input on the fitness of mitochondria, risking a discrepancy between the metabolic demands of the cell and the ability of the mitochondria to meet them.
Why there should be such a discrepancy between the two groups' fitness levels wasn't clear on the surface.
The failure also inspires attempts to understand the basis of the discrepancy between predicted and observed fitness.
In 1998, an inspection team audited the company's compliance with a state law that mandates driver fitness and training and found more than 200 discrepancies, according to testimony on Thursday from Thomas Fullington, an assistant director of the State Department of Motor Vehicles.
Given the considerable discrepancy in the observed and predicted genes under selection, fitness data have the great potential to improve systems biology models in the future.
Epistatic interactions among multiple simulated mutations according to their hypothetical impacts on fitness were evaluated; being the fitness a function of phenotypic discrepancies between mutant and optimal, or reference, spatio-temporal expression trajectories.
Its fitness metric function (to be minimized) presents the mean square error given through discrepancy value between model prediction and actual measurement for each sampling time.
One solution to this discrepancy is the hypothesis that Wolbachia has a positive influence on fitness of female D. melanogaster that compensates for its weak CI [21], [25], [26], but current evidence is mixed.
