Reproduction in Plants

Only one plant is required

Does not depend on external agents such as wind and animals

Relies on effective cross-pollination strategies to ensure pollen is transferred to a different plant of the same species

Offsprings can obtain favourable traits from both parents

Allows a particular species to colonies the area

Two plants required

Helps keep favourable traits in the species

More energy and pollen wasted

Less pollen and energy wasted

Due to changing environment, favourable traits may not be able to adapt in the future

Produces offsprings that are genetically similar, therefore loss of genetic variation

Increases genetic variation so that there are higher changes of survival of the species in changing environment

Can destroy well-adapted traits so offsprings may not be viable
