Question 1 of 7
All Questions (7)
A) Natural Selection
B) Artificial Selection
C) Genetic Drift
D) Random Mutation
Correct Answer: B
The text explicitly states, 'Through artificial selection, humans intentionally select for certain traits, thereby affecting the genetic variation in other species.'
A) To observe natural changes in a population without interference.
B) To increase the rate of random mutations.
C) To intentionally choose organisms with specific traits for breeding.
D) To document the existing genetic diversity of a species.
Correct Answer: C
The content specifies that 'humans intentionally select for certain traits,' which is the act of choosing which organisms will reproduce.
A) It increases overall diversity by introducing new species.
B) It has no measurable effect on a population's diversity.
C) It affects genetic variation by favoring human-selected traits.
D) It only affects the diversity of human populations.
Correct Answer: C
The text states that by selecting for certain traits, humans are 'affecting the genetic variation in other species,' which is a direct impact on diversity.
A) Only domesticated plants
B) Only microscopic organisms
C) Only the human population itself
D) Other species
Correct Answer: D
The text clearly indicates that artificial selection affects 'the genetic variation in other species.'
A) A population of bacteria develops resistance to an antibiotic over many generations.
B) A farmer breeds only the sheep that produce the softest wool.
C) A species of finch develops a different beak shape to adapt to a new food source.
D) A random genetic mutation causes a flower to have a new color.
Correct Answer: B
This scenario demonstrates a human intentionally selecting for a certain trait (soft wool), which directly aligns with the provided definition of artificial selection.
A) Environmental factors
B) Random chance
C) Human intention
D) The organisms themselves
Correct Answer: C
The text emphasizes that 'humans intentionally select for certain traits,' making human intention the driving force of the selection.
A) Human actions always increase the genetic diversity within populations of other species.
B) Through the deliberate choice of traits, humans can alter the genetic makeup and diversity of a species.
C) Populations change over time due to human activity, but this does not affect their genetic variation.
D) Artificial selection is a natural process that humans can observe but not influence.
Correct Answer: B
This option correctly combines the two main points of the text: humans 'intentionally select for certain traits' (deliberate choice) and this action is 'affecting the genetic variation' (altering the genetic makeup and diversity).
