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 another name for the sudden appearance of a new allele?

Another name for the sudden appearance of a new allele is called a mutation. Darwin called it a sport of nature.


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.


For a mutation to affect evolution it must occur in?

For a mutation to affect evolution, it must occur in the DNA of reproductive cells (sperm or egg cells) so that it can be passed on to offspring. Mutations that occur in somatic cells (non-reproductive cells) do not directly impact evolution as they are not inherited by future generations.


How do allele frequencies change in Hardy-Weinberg equilibrium?

In Hardy-Weinberg equilibrium, allele frequencies remain constant from generation to generation if certain conditions are met. These conditions include no mutation, no gene flow, random mating, a large population size, and no natural selection. If these conditions are not met, allele frequencies can change due to factors such as genetic drift, gene flow, mutation, non-random mating, or natural selection.

Which allele is associated with the BRCA2 mutation?

The BRCA2 mutation is associated with a variety of mutations across its gene. However, most commonly, the mutation is found in one allele of the BRCA2 gene located on chromosome 13.

Is homologous recombination a type of mutation?

No. A mutation can change an allele into any other allele. Homologous recombination can only change an allele to the allele of the homologous chromosome.

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 a permanent heritable change in an allele that produces a different variant of the same trait?

A permanent heritable change in an allele that produces a different variant of the same trait is called a mutation. Mutations can lead to genetic diversity within a population and are the raw material for evolution.

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 is dominant negative mutation?

A negative mutation is one which is harmful to the organism. The result of a negative mutation is a non-sense protein. Examples of negative mutations include:a frame shift mutation - codons are read wrongan insertion mutation - insertion of a sequence of extra nucleotidesa deletion mutation - deletion of a chain of nucleotidesa non-sense mutation - results in the creation of a non-sense proteina transition mutation - exchange of purines to pyrimidines thus changing the nucleotide sequence and resulting in a mutation.
