(20 cards)
Physical separation of members of a population.
Geographic Isolation
The form of selection where one extremes have more fitness than the average form.
Directional
The form of fitness where both extremes have more fitness than the average form.
Disruptive
The form of selection where one sex has traits to attract the other sex.
Sexual
The movement of an organism out of a population.
Emigration
The form of fitness where the average form has more fitness than the extremes.
Stabilizing
The movement of genes from one place to another.
Gene flow
The total genetic information available to a population.
Gene Pool
When people breed dogs to create new breeds.
Artificial selection
In which type of evolution to species become more and more similar?
Convergent
In which type of evolution do the organisms become more and more similar.
Divergent
In which evolution do the organisms become more and more dissimilar.
Coevolution
Structures that serve similar functions but may not look the same.
Analogous
Structures that are in an organism but serve no function.
Vestigial
Mating in a specific group.
Nonrandom mating
Study of genetics in terms of population
Population genetics
Structures that are similar in species.
Homologous
The phenomenon by which alleles change as a result of random events or chance.
Genetic drift.
The process that says the best adapted organism reproduces more successfully.
Natural selection
The change of characterized by periods of stability separated by great change.
Punctuated equilibrium
