- High susceptibility to diseases
- Greater genetic diversity within populations (correct)
- Limited genetic diversity within populations
- Produce infertile seeds
What does the genetic diversity in cross-pollinated plants contribute to?
What does the genetic diversity in cross-pollinated plants contribute to?
- Reduced yields in crop plants
- Wider range of physical traits and characteristics
- Increased resistance to diseases (correct)
- Decreased adaptability to environmental changes
Why is high fertility important for cross-pollinated crop plants?
Why is high fertility important for cross-pollinated crop plants?
- It makes them less adaptable to environmental changes
- It leads to decreased resistance to diseases
- It contributes to better yields (correct)

Study Notes
- Cross-pollinated plants have greater genetic diversity compared to self-pollinated plants
- This genetic diversity results in a wider range of physical traits and characteristics among individual plants
- Cross-pollinated plants are more adaptable to environmental changes, pests, and diseases due to their genetic diversity
- A subset of cross-pollinated plants is likely to thrive in varying conditions
- Cross-pollinated plants have high fertility, producing fertile seeds with diverse genetic makeup, contributing to better yields
- Genetic diversity in cross-pollinated plants leads to increased resistance to diseases, as not all plants in a population are susceptible to the same pathogens.
