What is genetic variation?

The process of natural selection

The presence of differences in DNA sequences among individuals in a population

The migration of individuals between populations

The process of genetic drift

What is the Hardy-Weinberg equilibrium?

A state where allele frequencies in a population remain constant from generation to generation

A method to artificially manipulate allele frequencies in a population

A process of rapid evolution

A state where allele frequencies in a population are constantly changing

Which of the following is an example of genetic drift?

A population of birds with different beak sizes survives a drought, leading to changes in allele frequencies

A large population of deer is split into two groups by a river, resulting in different mating behaviors

A small group of individuals from a population migrate to a new area, introducing new alleles to the gene pool

A population of bacteria evolves resistance to antibiotics over several generations

Which of the following statements about gene flow is true?

Gene flow increases genetic diversity within a population

Gene flow occurs only between individuals of the same species

Gene flow tends to decrease genetic differences between populations

Gene flow has no effect on the genetic composition of populations

What is the founder effect?

A phenomenon where allele frequencies change due to random sampling in a small population

A process where new alleles are introduced into a population through migration

A mechanism by which new species are formed

A model explaining the origin of life on Earth

Which of the following is an example of a selective pressure?

A sudden change in climate

The migration of individuals between populations

The random distribution of alleles in a population

The availability of food resources

What is the biological species concept?

A definition of a species based on the ability to interbreed and produce fertile offspring

A classification system based on physical characteristics

A concept that defines a species based on its geographic distribution

A theory that species evolve through natural selection

What is the molecular clock hypothesis?

A theory proposing that evolution occurs at a constant rate over time

A mechanism by which genes regulate the circadian rhythm

A method used to determine the age of fossils

A model explaining the relationship between DNA replication and protein synthesis

Which evolutionary force is responsible for speciation?

Gene flow

Genetic drift

Mutation

Natural selection

#10

What is a phylogenetic tree used for?

To track the movement of individuals within a population

To predict future evolutionary changes

To illustrate the evolutionary relationships between different species

To determine the age of fossils

#11

What is the bottleneck effect?

A process of genetic drift

The formation of new species

A mechanism of non-random mating

A reduction in the genetic diversity of a population due to a drastic reduction in population size
