Question

Cross-pollination is preferred over self-pollination because it?

• A. Produces better offspring
• B. Forms new varieties
• C. Induces parthenogenesis
• D. Is economical

Answer 1

The correct option is B Forms new varieties

• Cross-pollination can be defined as the transfer of pollen grains from the male reproductive organ (an anther or a male cone) of one plant to the female reproductive organ (a stigma or a female cone) of another plant.
• Insects and wind act as the agents of cross-pollination.
• Cross-pollination helps to produce varieties in species by recombinant genes while self-pollination maintains homozygosity.
  
• So the correct option is 'forms new varieties'.
