Biology Evolution

gene shuffling creates new variation by changing parts of the genetic code
gene pool all the genes within a population
directional selection occurs when natural selection favors one of the extreme variations of a trait
stabilizing selection both extremes are selected against
disruptive selection average phenotype selected against
gene flow members of one population move to another population and breed
genetic drift change in allele frequency due to random effects
bottleneck effect randomly remove large numbers of individuals from a population
founder effect small part of population removes itself from the larger population
geographical isolation separated by geographical barriers
behavioral selection separated by behavioral differences and don't mate
temporal isolation Don’t reproduce at the same time
reproductive isolation cannot mate and produce offspring
Hardy-Weinberg equilibrium allelic frequency stay the same
adaptive radiation species diversifies into many new species
convergent evolution species evolve to a similar form from different ancestors and adaptive to similar environment
coevolution species evolve together because of a close ecological relationship
punctuated equilibrium evolution shows long stable period and then rapid burst of change
