Front 1

natural selection

Back 1

differential survival and reproduction of individuals in a population

Front 2

evolution

Back 2

the change of allele frequencies in a population's gene pool over time

Front 3

population

Back 3

a group of organisms of the same species in the same area that share a common gene pool

Front 4

gene pool

Back 4

all the alleles at all the gene loci of all individuals in a population

Front 5

microevolution

Back 5

small scale changes in the genetic structure of a population from generation to generation

Front 6

hardy-weinberg theorem

Back 6

under certain conditions, the frequency of alleles in the population will remain the same from generation to generation

Front 7

genetic drift

Back 7

the effects of a small population size

Front 8

gene flow

Back 8

migration of individuals between 2 populations

Front 9

genetic fixation

Back 9

loss of all but one possible allele at a gene locus in a population

Front 10

bottleneck effect

Back 10

when a chance effect leads to a drastic reduction in population size

Front 11

founder effect

Back 11

when a group of individuals become separated from the larger parent population; the allelic frequencies in the gene pool may be different
