Question

Quizplus · Accepted Answer

Vertical transmission refers to the transmission of a disease from parent to offspring via milk, ovum, sperm, or placenta. This is in contrast to horizontal transmission, which occurs between individuals of the same generation through various means like respiratory route, contact, or common environment. Transmission between different species like higher and lower animals is also not considered vertical transmission.
