Define asexual reproduction.: A process resulting in the production of genetically identical offspring from one parent.
How many parents are involved in asexual reproduction?: One.
What cell division process produces offspring in asexual reproduction?: Mitosis.
What is a clone?: An organism that is genetically identical to its parent.
Give two examples of asexual reproduction in plants.: Runners (e.g. strawberry) and bulbs (e.g. daffodil).
What is binary fission?: The division of a single bacterial cell into two genetically identical daughter cells.
State one advantage of asexual reproduction in the wild.: An organism can reproduce rapidly without needing to find a mate.
State one disadvantage of asexual reproduction in the wild.: No genetic variation is produced, so the population may not survive environmental change or disease.
State one advantage of asexual reproduction in crop production.: All offspring have the same desirable characteristics as the parent plant.
State one disadvantage of asexual reproduction in crop production.: Lack of variation means the whole crop is equally vulnerable to disease.
How does sexual reproduction differ from asexual reproduction in terms of offspring genetics?: Sexual reproduction produces genetically different offspring; asexual reproduction produces genetically identical offspring.
What is budding?: A form of asexual reproduction where a new individual grows out from the parent's body, as seen in yeast and Hydra.
