What are nitrogen fixing bacteria?
Selection in which unique alleles are removed from the population
What is stabilizing selection?
A group of individuals capable of interbreeding
What is a species?
Prezygotic isolating mechanism in which organisms do not encounter each other
What is habitat isolation?
Inherited characteristics of organisms that enhance their survival and reproduction in specific environments
What are adaptations?
Photosynthetic bacteria which are often found in anoxic bodies of water.
What is cyanobacteria?
Sexual selection which leads to sexual dimorphism and contests of strength
What is male competition?
Evolutionary theory which suggests little change occurs in species followed by periods of rapid speciation
What is punctuated equilibrium?
Postzygotic isolating mechanism where offspring have reduced fertility.
What is hybrid breakdown?
Evolution when two non-related organisms begin to develop analogous traits.
What is convergent evolution?
A member of the Protista Kingdom that is algae, fungi, and animal-like.
What is a plasmodial slime mold?
A change in allele frequency due to changes in the environment.
What is natural selection?
General patterns of change in groups of related species that have occurred over broad periods of time
What is macroevolution?
Two species perform mating rituals at different times throughout the year
What is an example of temporal isolation?
It has been suggested that the phenotype of tan skin appearing in people from Ireland comes from survivors of the Spanish Armada washing up in Ireland. This is an example of

The mutualistic relationship between fungi and plants which provide nutrients to both
What is the mycorrhizae?
The exchange of DNA between non-sister chromatids during prophase I of meiosis
What is crossing over?
Structure in which chemical reactions occur within a semi-permeable membrane
What is a protobiont?
A form of reproductive isolation in which gametes are unable to survive within the fertilizing environment.
What is gametic isolation?
The total number of alleles for a trait in a population.
What is a gene pool?
The molecules which make up the cell walls of bacteria.
What are peptidoglycans?
An increase in fitness due to an organism possessing a dominant and recessive allele
What is heterozygote advantage?
The internal structure of chloroplasts which resembles the membrane of cyanobacteria
What is the thylakoid membrane?
When a human male is found out to have purchased fake Supreme/Gucci, no girl will date him. This is an example of which type of reproductive isolation
What is an example of behavioral isolation?
The result of different phenotypes appearing do to changes in nucleotide order.
What is variation?
