28 Specific grape varieties are maintained using stem cuttings from mature plants that are then planted and cultivated to produce grapes. This is an example of artificial asexual reproduction. What is a disadvantage of using asexual reproduction to produce fruit? A An outbreak of disease will affect the whole crop in the same way. B Genetically identical fruit is produced relatively quickly. C No pollination or pollinators are required. D The characteristics of the grapes will vary between plants.
