If all flowers in a type of plant were only capable of self-pollination, how would it affect the genetic diversity over several generations? Explain.
If plants only self-pollinate, genetic diversity declines continuously over generations because offspring receive genes solely from the same individual plant. This eliminates gene flow between distinct plants, preventing novel combinations of traits. Consequently, beneficial variations cannot spreadRead more
If plants only self-pollinate, genetic diversity declines continuously over generations because offspring receive genes solely from the same individual plant. This eliminates gene flow between distinct plants, preventing novel combinations of traits. Consequently, beneficial variations cannot spread, harmful traits can accumulate and the population becomes less adaptable and highly vulnerable to environmental shifts or disease outbreaks.

(i) Suitable methods: The farmer should utilize vegetative propagation methods such as stem cuttings, layering or micropropagation through plant tissue culture. (ii) Why effective: These asexual techniques bypass the slow seed development phase, rapidly generating thousands of disease-free, high-yielding plantlets from a single meristematic tissue sample while preserving uniform, desirable commercial traits without genetic variation.

See lessWhy do vegetatively propagated plants tend to be more vulnerable to diseases than sexually reproduced plants?
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 plRead more
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.
