| A | B |
|---|
| Species | population whoese members have the potential to interbreed and produce viable fertile offspring |
| Reproductive isolation | one group of genes becomes isolated from another to begin a sperate evoluttionary history. |
| Allopatric Speciation | Caused by a geogrpahic barrier |
| Sympatric Speciation | No geographic barrier. |
| polyploidy, habitat isolation, behaviral isolation, temporal isolation, and reproductive isolation are types of... | Sympatric isolation |
| Polyploidy | more than two complete sets of chromosomes 4n. |
| Habitat isolation | Two organism live in the same area but encounter each other rarely. |
| One snake is mainly terrestria, the other favors water is an example of | Habitat isolation |
| Behavioral isolation | Different mating dances cause this form of isolation |
| Temporal isolation | Isolated by time. |
| Bloom time of flowers is an example of ... | temporal isolation |
| Reproductive isolation | differences in sexual structures prevent copulation |
| Prezygotic barriers | Prevent mating |
| Postzygotic barriers | Prevent fertile offstpring once mating has occured. |
| Patterns of evolution are.... | divergent, convergent, parallel, coevolution, and adaption radiation |
| Population becomes isolated from the rest of the species and evolves into a new species | Divergent evolution |
| Unrelated species occupy the same environment and are subjected to similar selective pressures | Convergent evolution |
| two related species that have made similar evolutionary adaptations after their diveregence froma common ancestor | Parallel evolution |
| reciprocal evoluatioanry set of adaptations of two interacting species | Coevolution |
| Emergence of numerous species from a common ancestor introduced into an environment | Adaptive radiation |
