Consider an organism as a collection of inherited traits. Now consider each trait to be the expression of a single allele. An allele is a variant of a gene. For instance, if eye colour is coded for by a single gene, then there may be an allele A that codes for blue eyes, and an allele B that codes for brown eyes. A population gene pool, then, is the collection of all alleles present in a population of organisms from a single species. The allele frequency is the number of times a specific allele occurs in the population gene pool. For instance, the allele frequency of the brown-eye allele may be higher than the frequency of the blue-eye allele, meaning that more people have brown eyes than blue eyes, in this simplification.
Evolution is measured in terms of changing allele frequencies. For instance, in our example, we could measure the number of people with blue eyes in generation one, and then measure the number again in generation one hundred. If we see a significant shift in frequency, then evolution has occurred.
Nota bene: this is not how it works in reality, but it's easier to explain it in such simple terms than if I were to go into the complexities of population genetics.
Allele frequency is the rate of occurrence of an allele in the population gene pool.
Alleles are "rival" variants for the same gene. For instance, if hair colour is coded for by a single gene, then brown may be one allele for that gene, and blond another.
For humans, the population gene pool would consist of the collection of all copies of all alleles present in the population. Note that humans are diploid, so may carry two copies of an allele, or even rival alleles for the same gene at the same time.
The allele frequency is the number of copies of a particular allele found in that collection.
Evolution is often measured in terms of the changes in allele frequencies in population gene pools.
That's what evolution means: changes in allele frequencies.
The definition of evolution is the change in allele frequency over time in a population of organisms.
Achange in allele frequency is evolution!
Yes - the amount of absorption can depend on the frequency.
As genetic distance increases, the recombination frequency first increases in a linear fashion, but then levels off to a frequency of 0.5.
The relationship between gene pool and allele frequency is a relative relationship. Allele frequency is a relative percentage of the entire gene pool.
Population
divergent evolution
Evolution is the change in allele frequency in a given population over time. Revolution describes the motion of an object turning about its center.

Some observable traits in humans are dimples, earlobes, tongue-rolling, cleft chin, hairline, and freckles. The relationship between the frequency of a trait in a population and whether the trait is dominant or recessive because in inherited human traits, the offspring can either have dimples or no dimples.
The relationship between a population and a community is a niche.
speed = frequency x wavelength
The relation between evolution and adaptation is that in evolution and adaptation both the body causes some physical changes
It's a direct relationship; higher frequency gives you a higher pitch.
What is the relationship between electrical frequency and magnetic field speed for an ac machine
Wave speed = (Wavelength) times (frequency).
the higher the frequency, the higher the energy
Speed of the wave = frequency x wavelength
speed = frequency x wavelength
