1.
Adaptive Radiation: The diversification of one ancestral species into many descendent species
2.
Allele Frequency: The ratio of one allele to the total number of the alleles for that gene in the gene pool
3.
Behavioral Isolation: Isolation caused by differences in courtship or mating behaviors
4.
Bottleneck Effect: Genetic drift that occurs after an event greatly reduces the size of a population
5.
Coevolution: The process in which two or more species evolve in response to changes in each other
6.
Convergent Evolution: Evolution toward similar characteristics in unrelated species
7.
Directional Selection: The type of selection that favors phenotypes at one extreme of a trait's range
8.
Disruptive Selection: When two opposite, but equally uncommon, phenotypes are selected over the most common phenotype
9.
Divergent Evolution: When closely related species evolve in different directions, they become increasingly different...
10.
Evolution: - Genetic Drift
- Gene flow
- Mutation
- Sexual selection
- Natural Selection
11.
Extinction: The elimination of species from Earth
12.
Founder Effect: Genetic drift that occurs after a small number of individuals colonize a new area
13.
Gene flow: The movement of alleles from one population to another
14.
Gene Pool: The combined alleles of all of the individuals in a population
15.
Genetic Drift: Changes in allele frequencies that are due to chance and causes a loss of genetic diversity in a population
16.
Geographic Isolation: Involves physical barriers that divide a population into two or more groups
17.
Hardy-Weinberg equilibrium: - Very large population
- No Gene Flow
- No mutations
- No Sexual Selection
- No natural selection
18.
Intersexual Selection: When males display certain traits that attract the female
19.
Intrasexual Selection: Competition among males, and whoever wins the competition wins the female
20.
Microevolution: The observable change in the allele frequencies of a population over time
21.
Mutation: Random change in the DNA of a gene that can form a new allele
22.
Normal Distribution: The type of distribution in which the frequency is highest near the mean value and decreases toward each extreme end of the range
23.
p2+2pq+q2=1: Hardy-Weinberg Equilibrium
24.
Punctuated Equilibrium: The pattern that states episodes of speciation occur suddenly in geologic time and are followed by long periods of little evolutionary change
25.
Recombination: New allele combinations form in offspring through this process and mostly occur during meiosis
26.
Reproductive Isolation: When members of different populations can no longer mate successfully with one another
27.
Sexual Selection: When certain traits increase mating success
28.
Speciation: The rise of two or more species from one existing species
29.
Stabilizing Selection: The intermediate phenotype is favorite and becomes more common in the population
30.
Temporal Isolation: Exists when timing prevents reproduction between populations
