Step by step
Solved in 2 steps
- Describe the effect of malaria on the frequency of the HbS allele in areas where malaria is common:In areas with malaria, which individual would survive better and leave more offspring- an individual with two HbA alleles or an individual with one HbA allele and one HbS allele? Given this, would you expect the HbS allele to be common or rare in populations living with malaria?Describe what happens to allele frequencies as a result of the bottleneck effect. Discuss the relevance of this effect with regard to species that are approaching extinction.Does having a dominant allele mean that it will be found in greater frequency in the population? Explain
- Imagine you were to collect data from simulation 2 (negative selective pressure on SS genotypes) over five generations. The frequency of the S allele over time is graphed below. The graph shows a rapid decrease in the sickle cell allele frequency in the first generation but a slower decrease in later generations. By the fifth generation, the allele is not completely eliminated from the population. Provide two plausible explanations for why the S allele persists after five generations.Please explain why is it important to identify the carriers in a population for a rare allele to decrease the prevalence of the disease in the population by using the graph. Answer it by assuming that population is at Hardy Weinberg equilibrium.If the malaria parasite is eradicated from an area where it used to be prevalent; what would you expect to happen to the frequency of the HbS allele in the population living there?( find the source to support the information please)
