When is genetic drift a major factor in evolution?
When there is low gene flow When there is no selective pressure When there is a bottleneck
What drives the process of evolution?
Mutation, genetic drift and gene flow can all drive evolution to a degree and the last two, drift and flow, are especially powerful in small populations. But, the driver of adaptive change in all populations of organisms is natural selection.
What four factors can cause evolution to occur?
1.) Mutation 2.) Selection 3.) Gene Flow 4.) Genetic Drift
What is the modern definition of evolution based on population genetics?
The modern definition of evolution works at the level of genes, phenotypes and populations whereas Darwinism was mainly concerned with organisms, speciation and individuals. According to the modern definition of evolution, the populations evolve by changes in gene frequency brought about by random genetic drift, gene flow and natural selection. This change is gradual.
What is evolution and what does it involve?
Evolution is the change in allele frequency over time in a population of organisms; change over time. This is all that it involves and whether the driver of evolution is natural selection, the adaptive driver of evolution, genetic drift, a random process or gene flow between populations, gene frequencies in these populations change and that is all evolution involves. Now, how evolution occurs with it's various drivers is another question for another time.

When is genetic drift a major factor in evolution?
When there is low gene flow When there is no selective pressure When there is a bottleneck
When is genetic a major factor of evolution?

A random change in a population's allele frequency?
Evolution is the change in allele frequency over time in a population of organisms. By mutation, genetic drift, gene flow and natural selection.
What are the four ways evolution?
These four factors can effect ways evolution occur: 1.) Mutation 2.) Selection3.) Gene Flow4.) Genetic Drift
What is the mechanism of evolution?
The main driving mechanism of evolution is natural selection. Though genetic drigt and gene flow can also cause evolution.
What are the influences of evolution?
genetic drift, gene flow, mutation, natural selection and nonrandom mating ( sexual selection ).
