increases the frequency of certain alleles-the ones that contribute to reproductive success in a particular environment.
The only one of the four processes that leads to adaptation

Causes allele frequencies to cahnge randomly.
In some cases may cause alleles that decrease fitness to increase in frequency

Occurs when individuals leave one population, join another, and breed.
Allele frequencies may change because arriving individuals introduce alleles to their new population and departing individuals remove alleles from their old population

Modifies allele frequencies by continually introducing new alleles. 
These new alleles may be beneficial or deleterious or have no effect on fitness

Group of individuals from the same species that live in the same area at the same time and can interbreed

All alleles from all the gametes produced in each generation in a single group and then combine at random to form offspring

List the 5 assumptions that must be met to meet the Hardy-Weinberg Model

A nonrandom mating between relatives

Characteristics of inbreeding

The decline in average fitness that takes place when homozygosity increases and heterozygosity decreases in a population

The number of relative frequency of alleles that are present in a particular population

A form of nonrandom mating that does lead to changes in allele frequencies in the population and thus is a form of natural selection

A trait that is found in certain groups of organisms and their common ancestor, but is missing in more distant ancestors.

Species concept that the main criterion for identifying species is reproductive isolation.
