Use and disuse.
What is Lamarck's theory of how selection on phenotypes occurs?
100
A taxon that consists of all the evolutionary descendants of a common ancestor.
What is a clade?
100
The defining characteristic of a species.
What is the ability of its members to produce fertile offspring?
100
If the frequency of allele B is 0.75, this is the frequency of allele b (assuming only 2 alleles for the gene in a pop.).
What is 0.25?
100
The three domains of living things on Earth.
What are Archaea, Bacteria, and Eukarya?
200
Adaptations found in a population.
What is a favored trait that evolves through natural selection?
200
Similar traits that evolved independently in different lineages.
What is convergent evolution?
200
The root cause of speciation (in general).
What is reproductive isolation?
200
The meaning of the equation p^2 + 2pq + q^2
What is the genotype frequencies in a population at Hardy-Weinberg equilibrium?
200
An organism that obtains energy from inorganic substances and obtains carbon from carbon dioxide.
What is a chemolithotroph?
300
Examples include a population bottleneck and the founder's effect.
What is genetic drift?
300
Cells that can give rise to an entire organism.
What is a totipotent stem cell?
300
Changes in the courtship ritual of a species by certain members is an example of this.
What is behavioral isolation?
300
A population with more than one allele at a particular locus.
What is polymorphic?
300
These viruses specifically attack bacteria.
What is a bacteriophage?
400
Changes characteristics in a population by favoring phenotypes varying in both directions from the mean of the population.
What is disruptive selection?
400
A species known to be closely related to but phylogenetically outside the group of interest.
What is the outgroup?
400
The theory of speciation that predicts an inconsistent rate of new species with bursts of change and long periods of little change.
What is punctuated equilibrium?
400
Four of the factors that influence allele frequencies in Hardy-Weinberg equilibrium.
What are natural selection, nonrandom mating (sexual selection), mutation, genetic drift, and gene flow?
400
The idea that mitochondria and chloroplasts were once free living prokaryotes.
What is endosymbiotic theory?
500
This plant has almost 3 times as many genes as humans, due to many non-coding regions of DNA.
What is Rice?
500
Genes that contain the homeobox domain and specify pattern and axis formation in some animals.
What is a Hox Gene?
500
An area that forms when reproductive isolation is incomplete.
What is a hybrid zone?
500
If the frequency of the genotype AA is .16, this is the frequency of the genotype Aa.
What is 0.48?
500
These protists are the source of many of our oil and natural gas reserves, due to their decomposition over millions of years.
What are diatoms?
