The wings of a bird and the wings of an insect are:
| 1. | Homologous structures, represent divergent evolution |
| 2. | Analogous structures, represent convergent evolution |
| 3. | Phylogenetic structures, represent divergent evolution |

The eye of the octopus and the eye of the cat show different patterns of structure, yet they perform a similar function. This is an example of:
| 1. | Homologous organs that have evolved due to divergent evolution. |
| 2. | Analogous organs that have evolved due to convergent evolution. |
| 3. | Analogous organs that have evolved due to divergent evolution. |
| 4. | Homologous organs that have evolved due to convergent evolution. |
In a population of 1000 individuals, 360 belong to genotype AA, 480 to Aa and the remaining 160 to aa. Based on this data, the frequency of allele A in the population is:
1. 0.4
2. 0.5
3. 0.6
4. 0.7
Forelimbs of cat, lizard used in walking; forelimbs of whale used in swimming and forelimbs of bats used in flying are an example of:
1. Analogous organs
2. Adaptive radiation
3. Homologous organs
4. Convergent evolution
Variation in gene frequencies within populations can occur by chance rather than by natural selection.
This is referred to as:
1. Genetic drift
2. Random mating
3. Genetic load
4. Genetic flow
