How are alleles frequencies related to gene pools?
The frequency of the allele represents the percentage of that allele in the gene pool
A change in gene frequency in a population over time is a foundation of biological evolution true or false?
True. That is the definition of evolution.
When is a genetic drift a major factor of evolution?
When there is low gene flow.
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.
State the difference between geological evolution and organic evolution?
The word evolution has grown to be rather over-used and sometimes even misused, and is commonly used to refer to non-biological systems when talking about them in a sense of their changes over a period of time. For example, while computer systems do not evolve in the way biological organisms do, they have changed drastically over the years through a series of smaller changes. Outwardly this system appears very similar to biological evolution, and so evolution phraseology is useful in this context. Geologic evolution refers to a system of changes within a geological system. An example would be studying how a specific area has changed from ocean to mountains to desert over a period of time. Once again, geological systems do no progress in a "natural selection" sense such as true evolution, but they can change in drastic ways via a series of smaller changes over a very long period of time. Organic evolution presumably refers to a system of changes within a biological range. This could refer to the evolution of species or traits within a species, or may even relate to pre-biogenesis evolution of basic amino-acid strands.
How is evolution different in small populations?
isolated gene pools
How can a change in the gene pools evolution?
Not sure what you are asking, but, evolution is the change in allele frequency over time in a population of organisms.
Which of the various species concepts identifies species based on the degree of genetic exchange between their gene pools?
Biological species concept :)
How are alleles frequencies related to gene pools?

A change in gene frequency in a population over time is a foundation of biological evolution true or false?
True. That is the definition of evolution.
Why do gene pools lie at the root of evolution?
Basically because only populations ( populations gene pools ) evolve. Individuals die and any variant trait in their germ line must be passed into the gene pool. This way, in time, this trait may spread and the population evolves.
What is genetic evolution?
Genetic evolution refers to the variations in inherited traits of biological populations over successive generations. It is also referred to as the selfish gene theory.
What is the meaning of evolution?
Evolution is generally defined as "a series of changes over a period of time, resulting in something new arising". In particular, biological evolution is defined as "the change in frequency of alleles in a population's gene pool over a period of time".
How is cultural evolution similar to natural selection?
Cultural evolution is the phenomenon whereby cultural ideas, notions, views, etc. propagate throughout populations, like alleles propagate throughout population gene pools in biological evolution.Some propose that the way these ideas propagate throughout populations is similar to the ways of biological evolution, in that cultural ideas (or memes) are subject to a kind of cultural selection, that determines how fast they spread, and to what degree.
How is gene theory related to theory of evolution?
Genes are the hereditary molecules that natural selection actually selects, So, the change in allele ( different molecular form of the same gene ) frequency over time in a population of organisms is the definition of evolution.
Which is macroevolution?
Macroevolution is evolution on a scale of separated gene pools. Macroevolutionary studies focus on change that occurs at or above the level of species, in contrast with microevolution, which refers to smaller evolutionary changes
What is gene duplication?
Gene duplication is a key mechanism in evolution.
