Asexual Reproduction Chapter 10 Lesson 2

Important Things to Know Only one parent No meiosis or fertilization Offspring are identical to their parent

Fission DNA is copied DNA attaches to cell membrane and grows longer to make 2 new cells Examples: E. coli Streptococcus Bacillus anthracis

Mitotic Cell Division Form offspring through mitosis and cell division Example Amoeba

Budding An offspring grows through mitosis and cell division on the parent and then may or may not break off Example Hydra Yeast

Animal Regeneration A new organism grows from a part of the parent organism containing the central disk Example planarian sea star sea urchins sea cucumbers sponges

Vegetative Reproduction A new organism grows from the stolon of the parent organism Examples strawberries bananas potatoes geraniums

Cloning A new organism is produced in the lab from a cluster of cells from the parent organism Examples Fruits and Vegetables Sheep

Advantages of Asexual Reproduction Organisms can reproduce without a mate. Organisms can produce a large number of offspring.

Disadvantages of Asexual Reproduction Little genetic variation in a population May be harder for an organism to survive Mutations may be passed on to offspring
