Explain how geographic isolation can lead to allopatric speciation.
Explain how reproductive isolation can lead to sympatriic speciation.
What are two short comings of the biological species concept?
Describe one possible scenario of postzyogotic reproductuve isolation in an animal species.
PLEASE help me with these questions yes it is homework very hard for me answer what you can all answer help thank you very much (: have a really nice day guys (;

Explain how geographic isolation can lead to allopatric speciation.
- Being separated results in no gene flow so the species are more likely to change b/c of drift or mutation
Explain how reproductive isolation can lead to sympatric speciation.
- being reproductive isolated is the same as above no gene flow can cause a species that was once one species to then become 2 species
What are two short comings of the biological species concept?
- You can't depend on identifying a species based on appearance b/c some species may look the same but are really different and that concept doesn't take that into account... so b/c two look almost identical might get the same species name just b/c of looks
- also it says "potentially interbreeding" so where is that "jump" to breeding to not interbreeding? that phrase is not very specific and that's also a problem
Describe one possible scenario of postzyogotic reproductuve isolation in an animal species.
- Postzygotic... hybrid species tend to be fertile b/c they usually have an odd chromosome number (like mules)
