The chart above shows the allele frequencies for a normal hemoglobin (a allele) and a sickle cell hemoglobin (s allele).
which can correctly be inferred from the chart when looking at the allele frequency changes that have occurred over the
three generations?

B

Explanation:

There is a correlation between malaria infested regions and the allele frequency of sickle cell anemia, because the non sickle cell allele frequency is decreasing faster than the sickle cell allele frequency. The S allele is being selected for during natural selection in these areas. The S allele frequency is changing far less than the A allele frequency. This shows that the A allele is being selected against, therefore, there are far fewer of those alleles being inherited in each generation compared to the S allele. This selection of the S allele coincides with the correlation that exists in malaria infested areas and sickle cell anemia.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
