Sexual vs. Asexual Reproduction
This type of reproduction involves only one parent.
Asexual Reproduction
Traits you are born with.
Inherited Traits
This type of selection is controlled by humans.
Artificial Selection
Which type of reproduction produces identical offspring?
Asexual Reproduction
This type of reproduction creates more genetic diversity.
Sexual Reproduction
Learning how to ride a bike is this type of trait.
Acquired Trait
Farmers breeding cows to produce more milk is an example of this.
Artificial Selection
What does diversity mean?
A. All organisms are exactly the same
A. All organisms are exactly the same
C. Only the strongest organisms survive
D. Organisms reproduce quickly
B. Differences in traits among individuals in a population
Which type of reproduction would most likely help a species survive a sudden environmental change?
Sexual Reproduction
True or False: Acquired traits be passed to offspring?
False
Peppered moths changing color due to pollution is an example of this type of selection.
Natural Selection
Why is variation important in a population?
A. It allows all organisms to look exactly the same
B. It helps organisms survive changes in the environment
C. It prevents organisms from reproducing
D. It makes populations smaller
B: It helps organisms survive changes in the environment
Which organism would MOST likely reproduce asexually?

True or False: Artificial selection can reduce genetic diversity in a population.
True
True or False: Populations with little variation are more likely to survive environmental changes.
False
Which situation would MOST likely require sexual reproduction for survival?
A. A stable environment with no changes
B. A rapidly changing environment
C. An environment with unlimited resources

Which example best explains why acquired traits are not passed on?
A. They are controlled by DNA
B. They do not affect survival
C. They are not genetic
