Why do vegetatively propagated plants tend to be more vulnerable to diseases than sexually reproduced plants?

  • 1

Vegetatively propagated plants are genetically identical clones. Because they lack genetic diversity, any pathogen, pest or environmental change capable of harming one individual can rapidly wipe out the entire crop.

    1 Answer

    1. Plants produced through vegetative propagation share an identical genetic makeup derived from a single parent. Because no sexual recombination or meiosis occurs, there is zero genetic diversity within the population. Consequently, if a specific pathogen or pest overcomes the immune defense of one plant, all surrounding plants share the exact vulnerability, risking widespread crop devastation.
