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.
Mutation, migration, and genetic drift
There is no gene flow - APEX
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.
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.
Which factor might determine whether the frequency of the new allele will increase in a population where a mutation occurs?
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.
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.
Sickle cell anemia is found in high frequency because it is a codominant mutation. It only requires one allele for the gene to manifest.
