Front 1

change in the genetic message of a cell

Back 1

mutation

Front 2

genetic change in populations

Back 2

evolution

Front 3

organism's tendency to produce more offspring than competing individuals, and therefore contribute more genes to the next generation

Back 3

fitness

Front 4

-the frequency of the fit traits will increase in the population
-the nature of the population will change
-major force that guides genetic change and formation of new species

Back 4

natural selection

Front 5

the proportion of individuals in a certain category relative to the total number of individuals considered

Back 5

frequency

Front 6

principle that enables us to calculate and predict allelic and genotypic frequencies

Back 6

Hardy-Weinberg Principle

Front 7

equation that relates to frequencies of alleles at a particular gene locus

Back 7

p + q = 1

Front 8

equation that relates to frequencies of genotypes and phenotypes at a particular gene locus

Back 8

p^2 + 2 pq + q^2 = 1

Front 9

-population is large enough to overcome random events
-choice of mates is random
-mutation does not occur
-individuals do not migrate into or out of the population
-no selection pressure

Back 9

assumption of a stable population for the Hardy-Weinberg principle

Front 10

-the differential reproduction of phenotypes
-some phenotypes are passed to the next generation more often than others

Back 10

selection

Front 11

factors such as temperature and predation that affect organisms and result in selective reproduction of phenotypes

Back 11

selection pressures

Front 12

group of modern species of algae that reflects an easily recognized sequence of changes as their common ancestors evolved

Back 12

Volvocine line of algae
