Questions and Answers

Which of the following is a feature of cross-pollinated plants?

  • 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?

  • 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?

  • It makes them less adaptable to environmental changes
  • It leads to decreased resistance to diseases
  • It contributes to better yields (correct)
  • It reduces the genetic diversity within populations

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.
