Could you define Minor and major allele frequency?
A minor allele is the allele that has the least frequency among all the alleles in a given population and this has to be greater than 5%.
What is the distribution of a particular allele within a population called?
Based on the Hardy-Weinberg Principle the rate at which a particular allele occurs in a population is its frequency.
What happen when a population is in a Hardy equilibrium?
Allele frequency is stable The phenotype frequency does not change.
What happens when a population is in weinberg equilibrium?
Allele frequency is stable
What is the relationship between evolution allele frequency and 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.
How will the allele change in the rat population?
Evolution is the change in allele frequency over time in a population of organisms. Rats too!
What is the frequency of genotype AA if the frequencies of AA?
If the frequency of genotype AA is p^2, where p is the frequency of allele A, then the frequency of genotype AA would be p^2.
Describe what is occurring when a population is said to evolve?
The allele frequency of the populations gene pool is changing.
What Is the percentage of a particular allele in a population?
Allele frequency.
What effect does a bottleneck have on the allele frequency of a population?
A bottleneck can lead to a significant reduction in the genetic diversity of a population, causing certain alleles to be lost and others to become more common. This can increase the frequency of rare alleles and result in genetic drift, potentially leading to an increase in genetic diseases or reduced fitness in the population.
What is allele fixation?
An allele present in all members of a population
What is meant allele frequency?
How often a certain allele (or trait) occurs in a certain population.
If the actual allele frequencies in a population do not match genotype frequencies predicted by the Hardy Weinberg equation what is the population?
The population is evolving.
Could you define Minor and major allele frequency?
A minor allele is the allele that has the least frequency among all the alleles in a given population and this has to be greater than 5%.
In the Hardy Weinberg equation shown below P is the frequency of the dominant allele and q is the recessive allele?
Homozygous recessive genotype
What is the distribution of a particular allele within a population called?
Based on the Hardy-Weinberg Principle the rate at which a particular allele occurs in a population is its frequency.
Which is an example of genetic drift?
Allele frequencies change randomly each generation. APEX
