Answer 2

Answer:TWO

Explanation:

Plant viruses are generally spread by two common mechanisms:

horizontal transmission and vertical transmission

• Horizontal transmission: Generally, transmission of viruses can occur through two pathways: horizontal and vertical transmission. Here in horizontal transmission, viruses are transmitted among individuals of the same generation, while vertical transmission occurs from mothers to their offspring.
• Vertical transmission:The term “seed transmission” means the passage of the pathogen through seeds to seedlings and plants in the next generation.HIV, toxoplasma gondii, rubella, cytomegalovirus, and herpesviruses have been proven to transfer from mother to child via these routes, it is also known as vertical transmission . Vertical transmission plays an important role in the spread and survival of viroids, as well as viruses.
