List five conditions that can disrupt genetic equilibrium and cause evolution to occur
Colt1911 [192]
1. Non random mating
                                    In genetic equilibrium individuals must mate at random. However, in many species, individuals select mates based on heritable traits, such as size, strength, or coloration, a practice known as sexual selection.

2. Small population size
                                        Genetic drift does not have major effects on large populations but can affect small populations. Thus evolutionary change due to genetic drift happens more easily in small populations.

<span>3. Immigration or Emigration
                                                 Individuals who join a populations may introduce new alleles into the gene pool. Likewise individuals who leave may remove alleles from the gene pool. Any movement of individuals into (immigration) or out of (emigration) a population can disrupt genetic equilibrium, a process know as gene flow.

4. Mutations
                   Individuals who join a populations may introduce new alleles into the gene pool. Likewise individuals who leave may remove alleles from the gene pool. Any movement of individuals into (immigration) or out of (emigration) a population can disrupt genetic equilibrium, a process know as gene flow.

5. Natural Selection
 if different genotypes have different fitness, genetic equilibrium will be disrupted, and evolution will occur.</span>
