Question

What would be the consequence of organisms lacking variation?

Options

• Heredity would become more effective

• Offspring would not resemble their parents

• Populations would become too uniform, reducing their ability to adapt to changing conditions

• Natural selection would become stronger

Answer 1

Without variation, populations would become too uniform, which would reduce their ability to adapt to changing environmental conditions. Variation provides the diversity needed for populations to survive environmental changes and evolve.
