Transmission from parent to offspring is called:

• A. Vertical transmission
• B. Horizontal transmission
• C. Diagonal transmission
• D. Linear transmission

Answer: (A)

Vertical transmission describes transmission from parent to offspring. This includes the passage of genetic material from parent to child, as well as the transfer of pathogens during pregnancy, birth, or through breastfeeding. It explains how traits and infections can move along the parental line to the next generation, which is important for understanding heredity and colony health in research settings. Horizontal transmission, by contrast, occurs between individuals in the same generation and not along the lineage, so it doesn’t describe parent-to-offspring spread. The terms diagonal and linear transmission aren’t standard ways to describe this directional transfer and don’t capture the parent-to-offspring relationship.
