Variation and "drift" in the application and implementation of national policies and guidelines were also observed at different administrative levels.
Antigenic variation and drift are mechanisms by which pathogens change their exposed epitopes while maintaining protein function.
While the individual pathogens come from a range of divergent taxa, they share the common mechanisms of antigenic variation and drift to avoid clearance by the host immune system.
Traditionally, evolutionary theory focused on the interactions between phenotypic variation, selection, and drift, thereby accounting for small modifications of existing structures (Muller and Newman 2005).
While TT scholars generally accept the basic neo-Darwinian framework, they seek to understand variability in artifact traditions largely as outcomes of different cultural transmission systems rather than the strict undirected variation, selection, and drift model favored by the SND group.
Measurements on the noise behaviour, threshold variation and threshold drift are shown.
The relationship between reflection coefficient, load variation, and frequency drift is determined, which provides a reference for Q selection.
To solve this problem, the coagulated derivative is adopted in the paper; besides, the attitude dynamics equations derived in this paper take into account the effect of mass variation and the drift of orbital trajectory at the same time.
In addition to reduced genetic variation and genetic drift, local adaptation can also be constrained by variation in natural selection and gene flow [1], [12].
However if selective pressure is not constant, the potential for variation and or drift leading to subsequent sweeping haplotypes to have multiple differences from each other is increased.
