Biological Change Mechanism: Gene Flow-is this when there are different species interbreeding with eachother and making a subspecies?

Question

kainui · Answer

Not quite. Gene flow occurs when two separate populations of the same species interbreed. This happens during migration or immigration of some kind usually. An example would be easily seen in people. We're all the same species, but different populations have their own genes and alleles that causes us to look different. Imagine how different a Chinese person looks from an Irish person. If a bunch of Irish moved to China and had kids with the Chinese, their kids would be a mix of both and a prime example of gene flow! =D

Note that the genes could be alleles for something as obvious as hair color or for something as subtle as metabolism of a particular substance. Whenever an organism travels from one population (with a certain allele) to another (without that allele) and mates within the new population, there is potential for gene flow.
