Question

How does the selection process in transgenic animal production ensure that only beneficial genetic modifications are perpetuated?

पर्याय

• All animals expressing any foreign gene are equally selected regardless of phenotype

• The selection step identifies and chooses animals showing the desired character, ensuring only successfully expressed transgenes are used for breeding and research

• All transgenic animals are automatically beneficial and require no selection

• Selection occurs randomly without any scientific criteria

Answer 1

The selection process is a critical final quality assurance step in transgenic animal production. After confirming that the foreign gene has integrated and is being expressed, researchers carefully evaluate which animals display the desired phenotypic characters resulting from the transgene. For example, if engineering a cow for human protein production, only animals consistently producing the protein in milk at adequate levels would be selected. This selective approach ensures that only animals with functionally successful genetic modifications are used for breeding, research, or further development, preventing the propagation of ineffective or problematic modifications and maintaining the quality of transgenic lines.
