Options

  1. AA-4; B-3; C-1; D-2
  2. BA-2; B-4; C-1; D-3
  3. CA-4;B-2;C-3;D-1
  4. DA-3; B-1; C-4; D-2

Correct answer

C. A-4;B-2;C-3;D-1

Step-by-step solution

Gene Flow occurs through the migration of individuals between populations, introducing new alleles. Genetic Drift leads to random allele frequency changes in small populations due to chance. Natural Selection is illustrated by the peppered moth coloration example, where dark moths were favored in polluted areas. Bottleneck Effect occurs when a population's size is drastically reduced by a disaster, affecting genetic diversity.
