Which statement best describes natural selection?
Answer and explanation
Correct answer: B. Individuals with advantageous alleles are more likely to survive and pass those alleles on to offspring
- Step 1: Variation exists due to mutation and meiosis. Step 2. Selection pressures favour some phenotypes, so their alleles increase in frequency. Answer: Individuals with advantageous alleles are more likely to survive and pass those alleles on to offspring. Why not the others: alleles do not change in response to need; survival is not equal; inheritance of acquired characteristics is Lamarckism.
