What is it called when a new gene is incorporated into the germ cells (egg and sperm)?

• A. Genotyping
• B. Pronuclear injection
• C. Germline transmission
• D. Polymerase chain reaction

Answer: (C)

Germline transmission is the process by which a genetic change becomes part of the germ cells—egg and sperm—so it can be passed to future generations. When a new gene is incorporated into these cells, it can be inherited by offspring and appear in all cells of the developing organism, including its own germ cells, ensuring the trait persists beyond the individual. This is different from somatic changes, which affect only the treated organism and aren’t inherited. Pronuclear injection is a method used to introduce DNA into a fertilized egg with the goal of creating a heritable modification, while genotyping and PCR are techniques for analyzing DNA rather than describing inheritance patterns.
