| 2. | Analogous structures, represent convergent evolution |
| 3. | Phylogenetic structures, represent divergent evolution |

1. individuals mate selectively
2. there are no mutations
3. there is no migration
4. the population is large
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:

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. |
