| C. Gene flow | III. Sudden change in allele frequency |
| D. Mutation | IV. Analogous structures |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-IV, B-III, C-II, D-I
(A) Convergent evolution — this matches (IV) Analogous structures. In convergent evolution, different structures evolve to do the same work, so they look alike but have a different anatomy. The wings of a butterfly and of a bird are an example.
(B) Genetic drift — this matches (III) Sudden change in allele frequency. Genetic drift is a change in allele frequency that happens by chance, not because an allele is more useful. In a small population it can be large and quick.
(C) Gene flow — this matches (II) Migration of individuals. Gene flow, or gene migration, occurs when individuals move from one population to another. They add new alleles to the new population and remove alleles from the old one.
(D) Mutation — this matches (I) Change in base sequences. A mutation is a change in the base sequence of DNA. It creates new alleles, which is the raw material of variation.
