Allele frequency is the frequency (proportion) of alleles in a population. It can be expressed as a percentage or a decimal.
For example, suppose a population has 10 individuals and there are two alleles (A and a) of a gene. Suppose the individuals are as follows:
4 AA individuals = 8 A alleles
4 Aa individuals = 4 A alleles and 4 a alleles
2 aa individuals = 4 a alleles
So there are (8 + 4) = 12 A alleles in the population and (4 + 4) = 8 a alleles in the population.
The frequency of A alleles is therefore 12/20 = 0.6 or 60%.
The frequency of a alleles is 8/20 = 0.4 or 40%.
(Notice that the total number of alleles equals 1.0 or 100%.)
If an allele makes up one half of the frequency of a populations allele for a given trait it's allele frequency is?
its not anything.
Could you define Minor and major allele frequency?
Minor allele frequency (MAF) is the frequency at which the less common allele appears in a particular population. Major allele frequency (MAF) is the frequency at which the more common allele appears in a particular population. They are useful measures for studying genetic variation within populations.
The number of times an allele occurs in a gene pool?
The frequency of an allele in a gene pool is determined by counting the number of copies of that allele in a population. This frequency can change through evolutionary processes such as genetic drift, natural selection, mutation, and gene flow. Tracking allele frequencies helps scientists study population genetics and evolutionary dynamics.
Can the genotype in a population change with the allele frequency changing?
Yes, the ratios of genotypes for a specific trait can change if allele frequency changes.
What happens when a population is in Hardy m-Weinberg equilibrium?
Allele frequency is stable.(Apex)
What is an example of allele frequency?
An example of allele frequency is when in a population of 100 individuals, 60 individuals have the dominant allele (A) for a specific gene, while 40 individuals have the recessive allele (a). The frequency of the dominant allele (A) would be 0.6, and the frequency of the recessive allele (a) would be 0.4.
If an allele makes up one half of the frequency of a populations allele for a given trait it's allele frequency is?
its not anything.
The change in allele frequency?
Random change in allele frequency is called genetic drift.
Could you define Minor and major allele frequency?
Minor allele frequency (MAF) is the frequency at which the less common allele appears in a particular population. Major allele frequency (MAF) is the frequency at which the more common allele appears in a particular population. They are useful measures for studying genetic variation within populations.
How do you use Allele Frequency in a sentence for biology?
Allele frequency refers to the proportion of a specific allele in a population's gene pool. For example, in a population of birds, the allele frequency for the gene that determines feather color might be 0.7 for the brown allele and 0.3 for the white allele.

What Is the percentage of a particular allele in a population?
Allele frequency.
Can the genotype in a population change with the allele frequency changing?
Yes, the ratios of genotypes for a specific trait can change if allele frequency changes.
A particular gene pool contains only two alleles G and H for an inheritable trait If allele G has a relative frequency of 42 percent what is the relative frequency of allele H?
The relative frequency of allele H would be 58 percent (100% - 42% = 58%).
When a mutation first occurs a different allele is formed what best describes the frequency of this allele?
When a mutation first occurs, the frequency of the new allele is very low in the population. Over time, if the allele confers a selective advantage, it may increase in frequency through natural selection.
What is meant allele frequency?
How often a certain allele (or trait) occurs in a certain population.
What is relative allele frequency?
