  • Crossing between plants of the same variety
  • Introducing a gene to provide desired characteristics
  • Crossing between plants of different genera
  • Crossing between genetically dissimilar plants (correct)
  • How can desirable characteristics be incorporated into crop varieties?

  • By relying solely on intervarietal crossing
  • By introducing genes from unrelated genera
  • By using only interspecific crossing
  • By hybridisation and introducing specific genes (correct)
  • What is necessary for new varieties of crops to be accepted?

  • Being genetically identical to existing varieties
  • Being crossbred with unrelated species
  • Producing high yields under different conditions (correct)
