Mutation results in the generation of new alleles and contributes to genetic diversity or the size of the gene pool. Define the term gene pool.
Figure 1 below gives three scenarios, A, B and C, in which three separate mutations give rise to changes in the allele frequencies in a population of a particular animal.
Figure 1
Use your knowledge of mutations to state the meaning of the term silent mutation in Scenario B in Figure 1.
Referring to Figure 1, explain why Scenario B leads to a lower frequency of the new allele in the population than Scenario A.
Referring to Figure 1, explain why the mutation experienced in Scenario C will not remain in the population.
