The process in which one species splits into two or more species
Speciation
In natural selection, the selective agent is
the environment
When members of a population become a new species due to having different courtship rituals (singing, dancing, etc...) , this is called __________ isolation.
Behavioral
Florida panthers used to be more numerous in the Everglades. Today, there are only a few hundred left in the wild due to habitat loss and cars. Numbers are slowly recovering. Which genetic drift is this?
Bottleneck effect
Suppose a sea mount (little island in the ocean) forms from an underwater volcano. Birds from the mainland happen to colonize the island and no longer interbreed with the original population due to distance. What type of isolation?
Geographic
Give an example of one source of genetic variation for a population
Mutations (will also accept sexual reproduction)
This part of meiosis can help contribute to new genetic combinations in populations
Crossing Over
