genetic drift
allelic drift
the Sewall Wright effect

It might happen by genetic drift if the population is small enough.

Genetic drift is the name given to this loss of variation.

Most are caused by a random process known as genetic drift and have little effect.

Not all isolated populations will show evidence of genetic drift.

Genetic drift is rare and has little influence over evolutionary change.

Especially for your study of genetic drift in so-called stable species.

We showed that genetic drift can explain much of these frequencies.

Evolutionary change in small populations based on chance is called genetic drift.

"The point is, you don't get that high numbers by genetic drift alone.

One such is the role of genetic drift in speciation.

The random spread of genes is known as genetic drift.

Clearly we're talking about quite a large ship, with a population in the hundreds at least: high enough to prevent genetic drift.

Its frequency increased as a consequence of high genetic drift within this population.

These more random generational changes are described as genetic drift.

Random genetic drift may also cause the loss of mutations.

Genetic drift is the name given to random changes which remove variation from a population.

Genetic drift is usually less important than natural selection.

Perhaps we have reached the very pinnacle of natural selection and genetic drift.

The early migrants to America presumably spread over the land in small groups subject to what is called genetic drift.

They were interested in natural selection, genetic drift, and other aspects of population genetics.

Genetic drift is the effect of the sampling process that occurs in reproduction.

The populations are also small in size and would be noticeably affected by genetic drift.

Instead of all that genetic drift, the descolada must do the drifting.

The mechanisms of genetic drift can be illustrated with a simplified example.

Previous discussion on genetic drift examined just one cycle (generation) of the process.

Genetic drift (or allelic drift) is the change in the frequency of a gene variant (allele) in a population due to random sampling of organisms.

He was the chief developer of the mathematical theory of genetic drift, which is sometimes known as the Sewall Wright effect, cumulative stochastic changes in gene frequencies that arise from random births, deaths, and Mendelian segregations in reproduction.
