What effect does natural selection have on the allele frequency of a population?
In the next generation that trait increases in frequency above the frequency in the current generation.
The environment has changed and the frequency of the p allele has gone down what will this do to the q allele?
In a population's genetic makeup, if the frequency of the p allele decreases, it can lead to an increase in the frequency of the q allele if they are in a simple two-allele system (where p + q = 1). This is often the case in scenarios where the two alleles are in negative frequency-dependent selection, meaning that as one allele becomes less common, the other may benefit and increase in frequency. However, other factors such as selection pressures, mutation rates, and genetic drift can also influence the dynamics between p and q alleles.
What is member of a gene pair that determines a specific trait is?
an allele
A moth has two alleles for spots. It can have brown and white spots. The white spot allele frequency is 0.53. What is the brown spot allele frequency?
The total frequency of alleles in a population must equal 1. If the frequency of the white spot allele is 0.53, then the frequency of the brown spot allele can be calculated by subtracting the white allele frequency from 1. Therefore, the frequency of the brown spot allele is 1 - 0.53 = 0.47.
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.
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.
Will a dominant allele always increase in frequency 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.
What is the relationship between allele frequency and genotype frequency in a population?
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.
What would casue a mutated allele to increase in frequency in a population?
If it confered a reproductive advantage to the organism it resided in. This would drive representation of the allele higher in the populations gene pool; increase in frequency.
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 effect does natural selection have on the allele frequency of a population?
In the next generation that trait increases in frequency above the frequency in the current generation.
The environment has changed and the frequency of the p allele has gone down what will this do to the q allele?

However, other factors such as selection pressures, mutation rates, and genetic drift can also influence the dynamics between p and q alleles.
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.
What is member of a gene pair that determines a specific trait is?
an allele
What factor would cause a mutation that would cause an allele frequency to increase?
An increase in allele frequency can occur due to factors such as genetic drift, gene flow from other populations, natural selection favoring that allele, or a genetic mutation that confers a selective advantage.
A moth has two alleles for spots. It can have brown and white spots. The white spot allele frequency is 0.53. What is the brown spot allele frequency?
The total frequency of alleles in a population must equal 1. If the frequency of the white spot allele is 0.53, then the frequency of the brown spot allele can be calculated by subtracting the white allele frequency from 1. Therefore, the frequency of the brown spot allele is 1 - 0.53 = 0.47.
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.
