Regents Living Environment Evolution 2023 Flashcard

Front

What is selective breeding?

Back

Selective breeding is the process of choosing specific plants or animals to reproduce based on desired traits, such as size or disease resistance.

Front

True or False: A large seedless watermelon is a product of selective breeding.

Back

True

Front

What is one main factor that evolution relies on?

Back

Mutations in DNA are a primary factor that drives evolution by introducing genetic variation.

Front

True or False: Separating a population into two or more groups that cannot interbreed can lead to the formation of new species.

Back

True

Front

What is antibiotic resistance?

Back

Antibiotic resistance is the ability of bacteria to survive and reproduce despite the presence of antibiotics, often due to genetic mutations.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which a single ancestor species rapidly diversifies into a wide variety of forms to fill different ecological niches.

Front

What role do mutations play in evolution?

Back

Mutations introduce new genetic variations that can lead to changes in traits, which may be beneficial, neutral, or harmful.

Front

Define speciation.

Back

Speciation is the evolutionary process by which populations evolve to become distinct species.

Front

What is the significance of geographical isolation in evolution?

Back

Geographical isolation can prevent interbreeding between populations, leading to divergent evolution and the formation of new species.

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.
