A high-yielding variety of millet reproduces sexually. Scientists want its grain to contain more of a particular vitamin. No millet plants tested have the allele needed for this characteristic. A bacterium contains a gene that codes for a protein involved in making the vitamin.
Explain why genetic engineering is more suitable than selective breeding for producing this vitamin-enriched millet.
