Multiple Choice
Which statement best describes how reproduction leads to natural selection in a population?
A
Reproduction eliminates all genetic mutations, stabilizing the population's traits.
B
Reproduction increases genetic variation, allowing advantageous traits to become more common over generations.
C
Reproduction ensures that all individuals in a population have identical traits.
D
Reproduction decreases the genetic diversity within a population, leading to natural selection.
Verified step by step guidance
1
Understand the concept of natural selection: Natural selection is a process where individuals with advantageous traits are more likely to survive and reproduce, passing those traits to the next generation.
Recognize the role of genetic variation: Genetic variation within a population is crucial for natural selection because it provides a pool of different traits that can be selected for or against.
Identify how reproduction contributes to genetic variation: During reproduction, genetic material is mixed and recombined, leading to offspring with unique combinations of traits, increasing genetic diversity.
Evaluate the impact of advantageous traits: Traits that enhance survival and reproduction become more common in the population over generations, as individuals with these traits are more likely to reproduce successfully.
Conclude the relationship between reproduction and natural selection: Reproduction increases genetic variation, which is essential for natural selection to act upon, allowing advantageous traits to become more prevalent in the population.
