What is gene flow?

Back

Gene flow is the transfer of genetic variation from one population to another, which increases genetic diversity.

What is resource partitioning?

Back

Resource partitioning is when two species divide a resource based on differences in their behavior or morphology, allowing them to coexist.

Front

What is speciation?

Back

Speciation is the formation of a new species as a result of evolutionary processes.

What is the competitive exclusion principle?

Back

The competitive exclusion principle states that two species competing for the same resource cannot coexist if other ecological factors are constant.

Front

What is intraspecific competition?

Back

Intraspecific competition is competition among individuals of the same species for limited resources.

Front

What is interspecific competition?

Back

Interspecific competition is competition between individuals of different species for the same resources.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.
