Sentence examples for evolutionary frequency from inspiring English sources

The parasitic lifestyle is thought to have evolved 8 [ 3] to 11 [ 5] times in flowering plants, but comprehensive phylogenetic analyses have never been performed to investigate the evolutionary frequency and pattern of the shift to heterotrophy in angiosperms.

However, one must consider that random subunit fusions would conserve (dis)assembly in only a very small fraction of cases and thus the evolutionary frequency of (dis)assembly-conserving fusions is far higher than would be expected by chance.

The fact that a small fraction of genes in yeast are duplicated and that there are few relics or pseudogenes that were left behind [ 12- 15] suggests polyploidization and gene deletion events occur at low evolutionary frequencies in yeast.

In recent years, radar analysis of human motion using measurements of evolutionary Doppler frequency variations has been under intensive study [1 9].

A marked correlation was noted between evolutionary breakpoint frequency and gene density.

The evolutionary equilibrium frequency p i* was calculated by setting FA = FG, where pA + pG = 1. Figure 3a shows the phase diagram of equilibrium states for latitude l and harassment strength h.

To this end, a closed-form evolutionary wavenumber-frequency joint spectrum is first derived, and integrated readily with the updated spectral representation method.

We consider the reconstruction of signals from nonuniformly spaced samples using a projection onto convex sets (POCSs) implemented with the evolutionary time-frequency transform.

Indeed, as genomic aberrations are inherited by daughter cells and their prevalences vary over genes, different prevalences (roughly, evolutionary selection frequencies) of DNA copy number aberrations suggest different fitness contributions.

On the other hand, if the color morphs are maintained by negative frequency-dependent selection of a similar kind and magnitude across all populations, then at evolutionary equilibrium, morph frequency divergence should be significantly lower than neutral genetic divergence [ 15].

These tools include population dynamics, evolutionary game theory, frequency dependent selection and critical slowing down, genetic drift, and spatial diversity.
