Artificial Vs Natural Selection Flashcards
What is natural selection?
Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.
What is artificial selection?
Artificial selection is the intentional breeding of plants or animals to produce desired traits.
True or False: Natural selection occurs without human intervention.
True
Give an example of natural selection.
The peppered moth changing color in response to pollution is an example of natural selection.
Give an example of artificial selection.
The breeding of dogs for specific traits, such as size or temperament, is an example of artificial selection.
What is one pro of natural selection?
It promotes biodiversity and adaptation to changing environments.
What is one con of natural selection?
It can lead to the extinction of species that cannot adapt quickly enough.
What is one pro of artificial selection?
It allows for the rapid development of specific traits in organisms.
What is one con of artificial selection?
It can reduce genetic diversity and lead to health issues in bred populations.
Fill in the blank: Natural selection is a key mechanism of __________.
evolution
Multiple Choice: Which of the following is NOT a factor in natural selection? A) Variation B) Competition C) Genetic engineering
C) Genetic engineering
True or False: Artificial selection can lead to unintended consequences.
True
What is the role of variation in natural selection?
Variation provides the different traits that may be favored in a changing environment.
Fill in the blank: Artificial selection is often used in __________ agriculture.
modern
What is a consequence of reduced genetic diversity in artificial selection?
Increased vulnerability to diseases and environmental changes.
Multiple Choice: Which is a common practice in artificial selection? A) Survival of the fittest B) Selective breeding C) Natural adaptation
B) Selective breeding
What is the difference between selective breeding and natural selection?
Selective breeding is human-directed, while natural selection is driven by environmental pressures.
True or False: Both natural and artificial selection can lead to evolutionary changes.
True
What is an example of a trait that has been enhanced through artificial selection in plants?
Increased fruit size in cultivated tomatoes.
Fill in the blank: Natural selection can lead to __________ in species over time.
speciation
What is one way artificial selection impacts animal populations?
It can create breeds that are less able to survive in the wild.
Multiple Choice: Which of the following is a goal of artificial selection? A) Increase survival rates in wild populations B) Enhance specific traits C) Maintain genetic diversity
B) Enhance specific traits
What is a key factor that influences natural selection?
Environmental pressures such as climate, food availability, and predators.
True or False: Artificial selection can only occur in domesticated species.
False
Why might a species undergo natural selection?
To adapt to changes in their environment and improve their chances of survival.
