What are three mechanisms that cause allele frequency differences in a population?
Mutation, migration, and genetic drift
What is a founder mutation?
A founder mutation is a genetic alteration that is present in a population due to its ancestry from a small group of individuals who carried the mutation. This mutation can be passed down through generations, leading to a high frequency of the mutation in a specific population.
On what does the allelic frequency in a population depend?
The allelic frequency in a population depends on factors such as mutation rates, genetic drift, gene flow, and natural selection. These factors influence the proportion of different alleles within a population over time.
What do mutations do to alleles?
Generally, gene frequency will not change significantly unless the mutation is successful and advantageous enough that it is heavily selected in the population. Since most mutations result in failure of the organism to thrive (death, reproductive failure, etc.) they have little or no effect on a population's gene frequencies. Even if the mutation has no apparent detrimental effects it will, itself remain in the population at a low frequency unless it enhances the organism's ability to reproduce within the population.
How mutation can change the gene pool?
Mutations introduce new genetic variations into a population, which can affect the gene pool by altering allele frequencies. Mutations can create new alleles or change existing ones, leading to increased genetic diversity within the population. Over time, if these mutations are advantageous, they can become more common in the gene pool through natural selection, impacting the overall genetic composition of the population.
Under is condition would a mutation have most impact on allele frequency?
There is no gene flow.
When does a mutation have the mutation impact on allele frequency?
When the population is small or When there is no gene flow Small population, germ line mutation, beneficial mutation that gets into many progeny and a good deal of luck.
What causes a frequency in a population to change after each generation?
Gene mutation causes the phenotype frequency in a population to change after each generation.
When does mutation have a most impact on Allele frequency?
When the population is small or When there is no gene flow Small population, germ line mutation, beneficial mutation that gets into many progeny and a good deal of luck.

What is a founder mutation?
A founder mutation is a genetic alteration that is present in a population due to its ancestry from a small group of individuals who carried the mutation. This mutation can be passed down through generations, leading to a high frequency of the mutation in a specific population.
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 the one of the conditions for Hardy-Weinberg equilibrium?
One condition for Hardy-Weinberg equilibrium is a large population size, to prevent genetic drift from causing allele frequency changes.
What is A mutation that causes resistance in a population of beetles is an example of?
This is an example of natural selection, where the mutation provides a survival advantage to the beetles, allowing them to survive and reproduce more successfully than individuals without the mutation. Over time, the frequency of this mutation in the beetle population may increase as it becomes more prevalent in subsequent generations.
On what does the allelic frequency in a population depend?
The allelic frequency in a population depends on factors such as mutation rates, genetic drift, gene flow, and natural selection. These factors influence the proportion of different alleles within a population over time.
When does a mutation have the most impact on allele frequency?
There is no gene flow - APEX
What mutation has the greatest effect?
The mutation that has the greatest effect is one that is not only beneficial but that is heavily selected for by the environment. Ideally dominant as it will effect the population more rapidly than a recessive trait. Only traits that are selected for or against in a population change the frequency of the occurance of the alleles in the population.
