If malaria were eliminated how might the frequency of the sickle-cell allele change over time?

Since people with the sickle cell allele trait are resistent to malaria, if malaria were eliminated there would be no change in the frequncy of sickle cell allele. This is because the presense of malaria does not have an affect on patients with the sickle cell allele trait.

∙ 6y agoThe sickle cell allele frequency will increase if malaria is a significant selection pressure acting on that population, until the fatalities from sickle cell anemia begin to balance the survivors of malaria.
The sickle cell allele frequency will be unaffected or even decline if malaria is not a significant selection pressure acting on that population.
It all depends on the rate of malaria infection in the population!

What is an example of allele frequency?
The frequency for the mutant cystic fibrosis allele among Caucasians is 0.025, while the frequency of the normal allele is 0.975.
The number of times an allele occurs in a gene pool?
Think frequent. More of the allele in the populations gene pool and there is a change in the alleles frequency. Some goes for less of the allele.
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.
The change in allele frequency?
Random change in allele frequency is called genetic drift.
What question did Hardy and Weinberg want to answer?
To determine how allele frequency changes
What Is the percentage of a particular allele in a population?
Allele frequency.
What happens when a population is in hardy weinberg equillibrium?
You mama The allele frequency does not change.
Heterozygous persons with one sickle cell allele and one normal allele also show resistance to?
Malaria
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 effect does a bottleneck have on the allele frequency of a population?
It greatly reduces the total population, which increases the effects of genetic drift on allele frequency.
Can the genotype in a population change with the allele frequency changing?
Yes, the ratios of genotypes for a specific trait can change if allele frequency changes.
What is the Random change in a populations allele frequency is known?
Random change in allele frequency is called genetic drift.
