Nonselective, random evolutionary process altering allele frequencies which occurs in small populations.
What is genetic drift?
100
Can be observed to study the evolutionary history of organisms over a long period of time.
What are fossils?
100
Elements that are conserved along all domains of life as carriers of genetic information.
What is DNA and RNA?
200
A model that shows common ancestry between organisms.
What is a phylogenetic tree?
200
A genetic variation that is favored by selection and is manifested as a trait that acts as an advantage to an organism in its environment.
What is an adaptation?
200
Phenotypic variations are not created by environmental factors, but through...
What are random changes in DNA and new gene combinations?
200
Evidence for evolution and shared ancestry.
What are morphological homologies and biochemical/ genetic similarities?
200
Cellular process involving the construction and expression of genetic material (3).
What is transcription, translation, and replication?
300
Reasons for loss of genetic diversity.
What are inbreeding, small population size, nonrandom mating, the absence of migration, and a lack of mutations?
300
Influence evolutionary processes for small populations with not much genetic diversity.
What are chance and random events?
300
A heterozygous individual that carries the trait for Sickle Cell Anemia has an advantage due to...
What is resistance to malaria without the disease itself?
300
Remnants of functional structures that may no longer serve a function but indicate evolution (ex. appendix).
What is a vestigial structure?
300
A network of structural proteins that facilitate cell movement, morphological integrity and organelle transport.
What is a cytoskeleton?
400
Due to limited resources, individuals with favorable phenotypes or variations are more likely to survive and produce offspring passing on these traits to subsequent generations.
What is Darwin's Theory of Natural Selection?
400
Large population size, absence of migration, no net mutations, random mating, and absence of selection all describe a population in...
What is Hardy Weinberg Equilibrium?
400
Selection by humans that leads to a loss of genetic diversity in plant or animal species.
What is artificial selection?
400
Core elements that provide evidence for evolution.
What is are cytoskeletons, nuclei, membrane bound organelles, linear chromosomes, and endomembrane systems?
400
Two membrane bound organelles that show eukaryotic relatedness.
What is a chloroplast and mitochondria?
500
Mechanisms besides natural selection that contribute to genetic variation in populations.
What are mutations, genetic drift, sexual selection, artificial selection, and genetic engineering?
500
Using the Hardy Weinberg equation, the allele frequency of the dominant genotype is .64, so the allele frequency of the recessive genotype is...
What is .36?
500
There are light and dark peppered moths in an environment. After the introduction industrial processes, natural selection would act against...
What are light peppered moths?
500
An increased number of organisms are selected for with the trait to withstand the chemical pesticide.
What is DDT resistance?
500
The study of the living things' form and the relationships between organisms regarding their physical structures.
