Question

4.3.1 Test (CST): Unit Test The allele frequency of the mutant allele, a, is 15% in a particular population. Which scenario would be predicted to occur if malaria infections in this population increase dramatically in the future? A. There will be no change in allele frequencies, because the two selection pressures operate in opposing directions. B. The a allele frequency will increase, because heterozygous Aa individuals will be favored over homozygous AA individuals. C. Both A and a allele frequency will decrease, because there are selective pressures working against both of these alleles. D. The A allele frequency will increase, because normal alleles are superior to mutant alleles and improve survival.

          4.3.1 Test (CST): Unit Test
The allele frequency of the mutant allele, a, is 15% in a particular population.
Which scenario would be predicted to occur if malaria infections in this
population increase dramatically in the future?
A. There will be no change in allele frequencies, because the two
selection pressures operate in opposing directions.
B. The a allele frequency will increase, because heterozygous Aa
individuals will be favored over homozygous AA individuals.
C. Both A and a allele frequency will decrease, because there are
selective pressures working against both of these alleles.
D. The A allele frequency will increase, because normal alleles are
superior to mutant alleles and improve survival.
