What is a genetic bottleneck?

Back

A genetic bottleneck occurs when a major event, such as a natural disaster, drastically reduces the size of a population, leading to a loss of genetic diversity.

Front

What type of evidence is most useful in determining evolutionary relationships?

Back

Genetic sequences are the most useful type of evidence for determining evolutionary relationships among species.

Front

What is required for natural selection to occur in a population?

Back

Some genetic variation in the ancestral population is required for natural selection to occur.

Front

How does selection pressure affect genetic diversity?

Back

Genetic diversity can decrease due to selection pressure, as certain traits become more favorable and others are eliminated.

Front

What is convergent evolution?

Back

Convergent evolution is the process by which unrelated organisms develop similar traits due to living in similar environments.

Front

What is the significance of genetic variation in evolution?

Back

Genetic variation is crucial for evolution as it provides the raw material for natural selection to act upon.

Front

What is the role of mutation in evolution?

Back

Mutations introduce new genetic variations, which can lead to new traits that may be beneficial for survival and reproduction.

Front

What is the difference between natural selection and artificial selection?

Back

Natural selection occurs through environmental pressures, while artificial selection is driven by human choices in breeding.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which a single ancestral species rapidly diversifies into a wide variety of forms to adapt to different environments.

Front

What is the concept of survival of the fittest?

Back

Survival of the fittest refers to the idea that individuals with traits better suited to their environment are more likely to survive and reproduce.
