- Frequency is how many times something happens in a certain amount of time. It's like counting how many times your dog barks in a minute. Like if we know the speed of a wave, we can find its frequency. Imagine a wave like a roller coaster; how fast it goes up and down tells us its frequency.

The allele frequency is the number of individual alleles of a certain type, divided by the total number of alleles of all types in a population. In simple terms, the allele frequency describes how common an allele is within a population.
The allele frequency is different from the phenotypic ratioin that it accounts for all alleles, even if they are recessive and are “hidden” within carrier organisms. The phenotypic ratio only describes the phenotypes, or actual physical features that are present within a population. To find the allele frequency, scientists must consider heterozygou...
To find the number of alleles in a given population, you must look at all the phenotypes present. The phenotypes that represent the allele are often masked by dominant and recessive alleles working in conjunction. To analyze the allele frequency in a population, scientists use the Hardy-Weinberg (HW) equation.The Hardy-Weinberg equation is written ...
In a simplified scenario, p and q are the only alleles in the population, and the population is not developing any mutations.If this is the case, the sum of the allele frequencies of p and q must equal 1 because with only two alleles the combined frequency must equal 100%.
Trying to Find p First
One mistake that students commonly make is trying to calculate p by observing the population, then taking the square root. This does not work in typical recessive/dominant allele relationships, simply because a dominant allele can hide a recessive allele. For instance, if we were to calculate the square root of .84 (proportion of black rabbits), we would get nearly 92%. This overestimates the p allele frequency because of the fact that heterozygous phenotypes are actually hiding a recessive a...
Relating Allele Frequency to Fitness
A common misconception of allele frequency is that it is directly related to the evolutionary fitness of a particular allele. Just because an allele is frequent or infrequent has no bearing on the fitness of that allele.For example, many recessive traits that are deleterious “hide” in a population. This can mean that while it appears to exist at really low levels, it is in fact just hiding in the hybrids of the population. Other times, a new beneficial mutation will have a very low allele fre...

Aug 9, 2024 · In physics, the frequency of a wave is the number of wave crests that pass a point in one second (a wave crest is the peak of the wave). Hertz (symbol Hz) is the unit of frequency. The relationship between frequency and wavelength is expressed by the formula: [math]\displaystyle{ f = v/\lambda }[/math]
