Which of the following is NOT a technique used in genetic monitoring?

• A. Oocyte viability
• B. Biochemical markers
• C. Immune markers
• D. Breeding index determination

Answer: (A)

Genetic monitoring is about ensuring the colony’s genetic identity and integrity over time, using data that reveal who the animals are at the genetic level and how breeding choices affect diversity. Biochemical markers can reflect genotype-influenced metabolic states, immune markers can indicate genetic differences in immune function, and breeding index determination guides matings to maintain desired traits and avoid inbreeding. Oocyte viability, however, measures the health and potential of eggs for reproduction. While crucial for colony propagation, it doesn’t provide information about the genetic makeup or stability of the lineage, so it isn’t a technique used in genetic monitoring.
