total no of diversity of plants is equal to total no of genes
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.
The comparison between the number of copies of a particular allele and the total number of copies of a gene is referred to as allele frequency. Allele frequency represents how common an allele is in a population, expressed as a proportion or percentage of the total gene copies for that gene. It is a key concept in population genetics, helping to understand genetic diversity and evolutionary dynamics within a population.
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.
A gene locus refers to the specific position of a gene on a chromosome, while an allele refers to different versions of the same gene that can exist at a particular locus. In other words, a gene locus is the physical location of a gene on a chromosome, while an allele is a specific variant or form of that gene found at that locus.
Allele frequency, or gene frequency, is the proportion of a particular allele (variant of a gene) among all allele copies being considered. It can be formally defined as the percentage of all alleles at a given locus in a population gene pool represented by a particular allele.

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.

How often a certain allele (or trait) occurs in a certain population.
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.
Allele frequency, or gene frequency, is the proportion of a particular allele (variant of a gene) among all allele copies being considered. It can be formally defined as the percentage of all alleles at a given locus in a population gene pool represented by a particular allele.
The allele frequency in a population determines the genotype frequency. Allele frequency refers to how often a particular version of a gene appears in a population, while genotype frequency is the proportion of individuals with a specific genetic makeup. Changes in allele frequency can lead to changes in genotype frequency within a population over time.
No, a dominant allele will not always increase in frequency over time. The frequency of an allele in a population can be influenced by various factors such as natural selection, genetic drift, and gene flow.
