Evolutionary Factors Quiz

What is natural selection?

• The process by which certain traits or characteristics become more or less common in a population over time, based on their impact on survival and reproduction.

• The process by which certain traits or characteristics are passed down from parents to offspring.

• The process by which certain traits or characteristics are determined by external factors.

• The process by which certain traits or characteristics are randomly selected in a population over time.

How does genetic variation contribute to evolution?

• Genetic variation leads to extinction.

• Genetic variation has no impact on evolution.

• Genetic variation provides the raw material for natural selection.

• Genetic variation is only important in artificial selection.

What is gene flow and how does it affect evolution?

• Gene flow is the transfer of genetic material from one population to another through mutation, and it affects evolution by increasing the rate of mutations.

• Gene flow is the transfer of genetic material from one population to another through natural selection, and it affects evolution by favoring certain traits.

• Gene flow is the transfer of genetic material from one population to another through genetic drift, and it affects evolution by reducing genetic diversity.

• Gene flow is the transfer of genetic material from one population to another through migration or interbreeding, and it affects evolution by changing the gene pool and increasing genetic diversity.

Explain the concept of genetic drift and its role in evolution.

• Genetic drift is a deliberate change in allele frequency in a population over time, caused by natural selection.

• Genetic drift is a process that only occurs in small populations and has no effect on evolution.

• Genetic drift is a phenomenon that only affects non-essential traits and has no impact on survival or reproduction.

• Genetic drift is a random change in allele frequency in a population over time, caused by chance events. It can lead to the loss or fixation of certain alleles and is an important mechanism of evolution.

Give an example of an adaptation in organisms.

• Photosynthesis

• Camouflage

• Mutation

• Hibernation

Which evolutionary factor is responsible for the survival of the fittest?

• Genetic mutation

• Artificial selection

• Environmental adaptation

• Natural selection

How does genetic variation arise in a population?

• Genetic variation arises from natural selection, genetic drift, and genetic recombination.

• Genetic variation arises from genetic mutations, genetic recombination, and genetic isolation.

• Genetic variation arises from genetic mutations, genetic recombination, and genetic adaptation.

• Mutation, recombination, and gene flow.

What are the different types of genetic drift?

• bottleneck effect and founder effect

• genetic variation and genetic recombination

• natural selection and genetic recombination

• gene flow and genetic mutation

How does gene flow impact the genetic diversity of a population?

• Gene flow decreases genetic diversity.

• Gene flow has no impact on genetic diversity.

• Gene flow increases genetic diversity.

• Gene flow only impacts genetic diversity in certain populations.

What are some examples of natural selection in action?

• Evolution of antibiotic resistance in bacteria, development of pesticide resistance in insects, adaptation of finch beak size

• Evolution of antibiotic resistance in humans, development of pesticide resistance in plants, adaptation of bird wing size
