Based on Figure 22.10, for natural selection to act on variations within a population, which two conditions must be met?

  • A: The variations must be visually appealing and increase reproductive rate.
  • B: The variations must be heritable and affect the individuals' ability to survive and reproduce.

  • D: The variations must be a result of artificial selection and be advantageous.

Figure 22.10's caption explicitly states that natural selection may act on variations only if 1 they are heritable and 2 they affect the beetles' ability to survive and reproduce.
