Question

How does poor adaptability to changing environments result from self-pollination?

Options

• External agents are essential for plants to adapt to new environments

• Self-pollinating plants are naturally more sensitive to temperature changes

• Lack of genetic diversity limits the variety of traits available for natural selection to act upon

• Defective characters enhance the plant's ability to survive

Answer 1

Self-pollination results in poor adaptability to changing environments because genetic diversity is reduced. With limited genetic variation, natural selection has fewer phenotypic traits to act upon, reducing the population's capacity to evolve in response to environmental changes.
