100
Humans breeding certain plants and animals to enhance desired traits.
What is artificial selection?
100
Category that includes Natural selection, mate choice, migration, mutation and genetic drift
What is microevolution?
100
The study of the frequency and interaction of alleles and genes in populations
What is population genetics?
100
A state in which a population can no longer interbreed with other populations to produce future generations
What is reproductive isolation?
200
Name another scientist who proposed a theory to explain evolution? What was his theory?
Who is Lamarck? What is the theory of acquired traits?
200
Four components of natural selection, in order.
What are...
genetic variation
overproduction of offspring
struggle for existence
differential survival and reproduction
200
Species evolve together and have adaptations to one another
What is coevolution?
200
A state in which the allele frequencies of a population remain in the same ratios from one generation to the next
What is genetic equilibrium?
200
Populations that are different from but can still interbreed with other populations of the same species
What is subspecies?
300
Four areas of science that support Darwin's theory of evolution?
What are...
1. the fossil record
2. Biogeography
3. Developmental Biology
4. Anatomy (homologous structures)
5. Biochemistry
300
Occurs when one phenotypic extreme is favored over another
What is directional selection?
300
All individuals of a species (lineage) die off or fail to reproduce
What is extinction?
300
Predicts that the frequencies of alleles and genotypes will not change unless 1 of 5 things acts on it:
gene flow
nonrandom mating
genetic drift
mutation
natural selection
What is Hardy-Weinberg Principle?
300
Species concept primarily based on the requirement of reproductive isolation
What is the biological species concept?
400
Difference between a law and a theory.
What is a law describes a natural phenomenon, while a theory describes how a natural phenomenon happens?
400
The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals
What is natural selection?
400
Theory of species gradually changing over time
What is gradualism?
400
A trait that has more than two possible phenotypes that are caused by multiple genes controlling the trait
What is polygenic trait?
400
The formation of new species by natural selection as a means for evolution
What is speciation?
500
The role that sexual reproduction plays on evolution.
What is it creates the possibility that mating patterns or behaviors can influence the gene pool of a population?
500
Graph that shows most of the population in the middle rather than the extremes.
What is normal distribution?
500
Patterns seen in evolution such as convergent evolution, coevolution, adaptive radiation, extinction, gradualism, and punctuated equilibrium
What is macroevolution?
500
In a population that has a common occurrence of Huntington's disease, a disease caused by a single dominant allele. Given the the frequencies below, predict the percentage of the population that would NOT get the disease.
p = .32
q = .68
p2 + 2pq + q2 = 1
What is 46%?
500
Speciation that occurs because organisms reproduce at different times of the year
