What is the definition of Genetic Drift?
This mechanism of evolution introduces new genes into the gene pool which results in increased genetic variability and new traits present in the population.
This mechanism of evolution results usually after a drastic decrease in the population size (like being stranded on an island) leaving only those genes present in the remaining individuals in the gene pool. This change in the allele frequency, ultimately changes the phenotypes most common in the population.
The mechanism of evolution that results from the migration of organisms into a new population or out of a population, changing the gene pool of each population.
This mechanism of evolution results when those organisms most fit for an environment survive and reproduce better than others in the population.

What's the definition of non-random mating?
This mechanism of evolution results by the likelihood that organisms select their mate based on certain criteria such as color, size, song, or other mating behaviors
This mechanism of evolution results when those organisms most fit for an environment survive and reproduce better than others in the population.
The mechanism of evolution that results from the migration of organisms into a new population or out of a population, changing the gene pool of each population.
