Mutations are important because they bring about
death of the organism in which they develop
genetic variation needed for a population to evolve
benefits for the individual, not for the population
Hardey-Weinberg equilibrium within a population
Why has antibiotic resistance evolved in bacteria?
Bacteria reproduce quickly
Bacteria with a resistance to the antibiotic, passed that trait to offspring
Bacteria that are resistant reproduce faster than non resistant strains
Bacteria exposed to antibiotics develop a resistance to them
Genetic drift is change in the allele frequency of a population due to...
random chance
natural selection
non-random mating (sexual selection)
artificial selection
A(n)________ is a measure of how common a certain allele is in a population.
Allele Frequency
Gene Pool
Genotypical Number
Genetic Drift
A small group of squirrels gets separates them from the rest of the population due to a large flood. These squirrels, now confined to this new island, begin to start a new population. This is an example of which of the following?
Founder effect
Bottleneck effect
Natural Selection
Gene Flow
The exchange of genes between two populations.
Genetic Drift
Founder Effect
Gene Flow
Genetic Recombination
This is a pattern of natural selection where one extreme form of a trait is more advantageous than the average or the opposite extreme; as a result, this trait in the population tends to evolve towards that one extreme
Directional selection
Disruptive selection
Stabilizing selection
Forward selection
This is a pattern of natural selection in which the average (or intermediate) form of a trait is the most advantageous, and so a population evolves away from the extremes and toward the average
Disruptive selection
Directional selection
Stabilizing selection
Middle selection

homologous structure
vestigial structure
What is this an example of?
Homologous structure
Analogous structure
Vestigial organs
Functional adaption
What conclusion can you draw from the fact that many modern whale species have vestigial pelvic and leg bones?
The ancestors of whales may have been land mammals
Whales could walk if they wanted to
Whales are preparing to evolve into land animals
Someday whales will be able to walk and will have legs
What conclusions can be made based on this table shown?
the American black bear and the giant panda are most closely related
the giant panda and the red panda are most closely related
the red panda and the racoon are the most closely related
the giant panda and the racoon are most closely related
