AP Biology

Speciation Modes

AP Biology

*Speciation can take place with or without geographic isolation

*Reproductive isolation prevents gene flow between populations, and eventually populations become distinct species.

AP Biology

Allopatric speciation * Can lead to

reproductive

isolation

Populations

geographically

isolated

AP Biology

Sympatric Speciation Speciation is occurring in populations

in same geographic area

How does this happen? Polyploidy Habitat differentiation Sexual selection

AP Biology

Polyploidy Extra sets of chromosomes

AP Biology

Habitat Differentiation Use habitat differently

Ex. Fish population with some individuals using bottom and other fish using the top area

AP Biology

Sexual Selection
